spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1.

Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

The named commit: - ignored the responsible arguments (speed, mode) The set speed/mode function must use the supplied function arguments to work properly. With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

The named commit: - ignored the responsible arguments (speed, mode) The set speed/mode function must use the supplied function arguments to work properly. With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support).

The named commit: - ignored the responsible arguments (speed, mode) The set speed/mode function must use the supplied function arguments to work properly. With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

dm: Rename dev_addr..() functions These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI* This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

The named commit: - ignored the responsible arguments (speed, mode) The set speed/mode function must use the supplied function arguments to work properly. With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

dm: Rename dev_addr..() functions These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

spi: omap3: fix set_wordlen() reading from incorrect address for CHCONF _omap3_spi_set_wordlen() indexed the regs->channel[] array with the old wordlen (instead of the chipselect number) when reading the current CHCONF register value. This meant it read from the wrong memory location, modified that value, and then wrote it back to the correct CHCONF register. The end result is that most slave configuration settings would be lost, such as clock divisor, clock/chipselect polarities, etc. Fixes: 77b8d04854f4 ("spi: omap3: Convert to driver model") Signed-off-by: David Rivshin <drivshin@allworx.com> |

spi: omap3: fix claim/release bus within DM The claim/release bus function must not reset the whole SPI core because settings regarding wordlen, clock-frequency and so on made by set_wordlen, set_mode, set_speed get lost with this action. Resulting in a non-functional SPI. Without DM the failure didn't came up since after the spi_reset within claim bus all the setup (wordlen, mode, ...) was called, in DM they are called by the spi uclass. We change now the things as following for having a working SPI instance in DM: - move the spi_reset(...) to the probe call in DM for having a known hardware state after probe. Without DM we don't have a probe call, so we issue the reset as before during the claim_bus call. - in release bus we just reset the modulctrl to the reset-value (spi- slave) Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Reviewed-by: Jagan Teki <jagan@openedev.com> |

With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents.

Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

omap: spi: Drop CONFIG_OMAP3_SPI_D0_D1_SWAPPED support This particular quirk is not enabled in any config files today. It does however exist and is handled correctly in device trees and via CONFIG_DM_SPI. So we drop the symbol now and add a comment to indicate that any (new) boards that require this quirk need to enable DM_SPI instead. Signed-off-by: Tom Rini <trini@konsulko.com>

dm: core: Replace of_offset with accessor At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

omap3: Fix SPI registers on am33xx and am43xx When the base registers are read from device tree the base is not 0x48030100 as the driver expects, but 0x48030000, resulting in non functioning SPI. To deal with this, use same idea as how this is done in the linux kernel (drivers/spi/spi-omap2-mcspi.c) and add a structure with a field that is used to shift the registers on these systems. v2: Fixed commit subject line to correct cpu Signed-off-by: Martin Hejnfelt <mh@newtec.dk>

spi: omap3: Fix multiple definition of 'priv' Global definition of priv seems no-sense to use it for non-dm case and pass the pointer to functions which are common to both dm and non-dm. So, fix this by removing omap3_spi_slave from non-dm and make visible to omap3_spi_priv for both dm and non-dm.

spi: omap3: add support for more word lengths Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.
