powerpc: Remove duplicate/unnecessary ifdefs When an ifdef is used in the below manner, second one could be considered as duplicate. ifdef DEFINE_A ...code block... ifdef DEFINE_A <-- This is a duplicate. ...code block... endif else ifndef DEFINE_A <-- This is also duplicate. ...code block... endif endif More details about the script and methods used to find these code patterns are in cover letter of [1]. Few places in arch/powerpc where this pattern was seen: paca.h: Hunk1: Code is under check of CONFIG_PPC64 from line 13, hence the second CONFIG_PPC64 at line 166 is a duplicate. Hunk2: CONFIG_PPC_BOOK3S_64 was defined back to back. Merged the two ifdefs. asm-offsets.c: Code is under check of CONFIG_PPC64 from line 176 hence second CONFIG_PPC64 at line 249 is a duplicate. powermac/feature.c: #ifndef CONFIG_PPC64 is used at line 2066. And then in #else again #ifdef CONFIG_PPC64 is used. Which is a duplicate since in #else means CONFIG_PPC64 is defined. xmon.c: Code is under the check of CONFIG_SMP from line 521 hence the same check of CONFIG_SMP at line 646 is a duplicate. No functional change is intended here. It only aims to improve code readability.

[POWERPC] Disable G5 NAP mode during SMU commands on U3 It appears that with the U3 northbridge, if the processor is in NAP mode the whole time while waiting for an SMU command to complete, then the SMU will fail. It could be related to the weird backward mechanism the SMU uses to get to system memory via i2c to the northbridge that doesn't operate properly when the said bridge is in napping along with the CPU. That is on U3 at least, U4 doesn't seem to be affected. This didn't show before NO_HZ as the timer wakeup was enough to make it work it seems, but that is no longer the case. This fixes it by disabling NAP mode on those machines while an SMU command is in flight.

[POWERPC] powermac: Constify & voidify get_property() Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powermac platform & macintosh driver changes.

[PATCH] powerpc: Kill _machine and hard-coded platform numbers This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

[PATCH] powermac: Fix loss of ethernet PHY on sleep Some recent PowerBook models tend to lose the ethernet PHY on suspend/resume. It -seems- that they use a combo ethernet-firewire PHY chip and the firewire PHY seems to die the same way when that happens. Not trying to toggle the firewire cable power appears to fix it. So this patch disables changes to the firewire cable power control GPIO on those models.

[SUNGEM]: Make PM of PHYs more reliable (#2) On my latest laptop, I've had occasional PHY dead on wakeup from sleep... the PHY would be totally unresponsive even to toggling the hard reset line until the machine is powered down... Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.

[PATCH] 3/5 powerpc: Add platform functions interpreter This is the platform function interpreter itself along with the backends for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).

[PATCH] 1/5 powerpc: Rework PowerMac i2c part 1 This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

[PATCH] powerpc: Experimental support for new G5 Macs (#2) This adds some very basic support for the new machines, including the Quad G5 (tested), and other new dual core based machines and iMac G5 iSight (untested). This is still experimental ! There is no thermal control yet, there is no proper handing of MSIs, etc.. but it boots, I have all 4 cores up on my machine. Compared to the previous version of this patch, this one adds DART IOMMU support for the U4 chipset and thus should work fine on setups with more than 2Gb of RAM.

[PATCH] powerpc: Remove device_node addrs/n_addr The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code.

[PATCH] powerpc: Unify udbg (#2) This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.
