2013-08-01powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)Aaro Koskinen1-9/+9
slots-fan on G5 Xserve is always running at full speed with windfarm_rm31 driver, resulting in a very high acoustic noise level. It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.

2013-01-03Drivers: macintosh: remove __dev* attributes.Greg Kroah-Hartman1-1/+1
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-04-30powerpc/powermac: New windfarm driver for PowerMac G5 (AGP) and Xserve G5Benjamin Herrenschmidt1-0/+740
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.
