# 239398 19-Aug-2012 andreast

Avoid using the degree symbol. Looks ugly on the console.


# 227293 07-Nov-2011 ed

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

Move the celsius-to-kelvin conversion to a place that powermac_thermal can
see it as well.


# 222458 29-May-2011 nwhitehorn

Update the I2C-based temperature/fan drivers to connect to the Powermac
thermal control module. This provides automatic fan management on all G5
PowerMacs and Xserves.


# 217452 15-Jan-2011 andreast

Remove unused variable. Spotted by a cppcheck
(devel/cppcheck, http://sourceforge.net/projects/cppcheck) run.

# 213904 15-Oct-2010 andreast

Add three new drivers for fan control and temperature reading on the
PowerMac7,2.

- The fcu driver lets us read and write the fan RPMs for all fans in the
PowerMac7,2. This driver is PowerMac specific.
- The ds1775 is a driver to read the temperature for the drive bay sensor.
- The max6690 is another driver to read temperatures. Here it is used to
read the inlet, the backside and the U3 heatsink temperature.

An additional driver, the ad7417, will follow later.

Thanks to nwhitehorn for guiding me through this driver development.
