# 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.


# 217560 18-Jan-2011 andreast

There are PowerMacs which do not have a hwsensor-location property
for this sensor. Instead of leaving this location empty we use here
the default name 'sensor'.

# 216360 10-Dec-2010 andreast

On the Xserve G5 we find the LM75 instead of the DS1775. The core
functionality is the same, a difference is that the DS1775 has a better
precision than the LM75. But we do not use it in our setup. Make the
LM75 work the same as the DS1775.

Fix a typo in device_set_desc.

# 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.
