Benjamin Herrenschmidt 6cd3209967 powerpc/powermac: New windfarm driver for PowerMac G5 (AGP) and Xserve G5
This replaces the old therm_pm72 using the same windfarm infrastructure
that was used for other PowerMac G5 models. The fan speeds and sensors
should now be visible in the same location in sysfs.

The driver is split into separate core modules for PowerMac7,2 (and 7,3)
and RackMac3,1, with a lot of the shared code now in the separate sensor
and control modules.

Benjamin Herrenschmidt e074d08e2b powerpc/windfarm: const'ify and add "priv" field to controls & sensors
const'ify the sensor ops and name and add a void* for use by
the control and sensor drivers to point back to their private
data, avoiding the need to create a wrapper data structure
per sensor or control instance.

Benjamin Herrenschmidt ac171c4666 [PATCH] powerpc: Thermal control for dual core G5s
This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

Benjamin Herrenschmidt 75722d3992 [PATCH] ppc64: Thermal control for SMU based machines
This adds a new thermal control framework for PowerMac, along with the
implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and
PowerMac9,1 (latest single CPU desktop). In the future, I expect to move
the older G5 thermal control to the new framework as well.
