powerpc/windfarm: Fix XServe G5 fan control Makefile issue

2013-11-27T00:35:47Z

We are missing building windfarm_max6690_sensor.o when building CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built and thus this isn't a problem but some more "tailored" setups (Gentoo ?) building only that driver are not working because the require sensor module is missing.

powerpc/pmu: Fix ADB_PMU_LED_IDE dependencies

2013-10-31T01:37:29Z

for quite some time the following is printed (twice) after doing "make oldconfig": [...] scripts/kconfig/conf --oldconfig Kconfig warning: (ADB_PMU_LED_IDE) selects LEDS_TRIGGER_IDE_DISK which has unmet direct dependencies (NEW_LEDS && IDE_GD_ATA && LEDS_TRIGGERS) warning: (ADB_PMU_LED_IDE) selects LEDS_TRIGGER_IDE_DISK which has unmet direct dependencies (NEW_LEDS && IDE_GD_ATA && LEDS_TRIGGERS) The following patch causes ADB_PMU_LED to depend on IDE_GD_ATA, so that the options above are only available when IDE_GD_ATA is actually selected and thus eliminates the warning.

drivers: clean-up prom.h implicit includes

Powerpc is a mess of implicit includes by prom.h. Add the necessary explicit includes to drivers in preparation of prom.h cleanup. Signed-off-by: Rob Herring Acked-by: Grant Likely

macintosh/ams: Replace strict_strtoul() with kstrtoul()

2013-08-14T04:57:43Z

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Signed-off-by: Benjamin Herrenschmidt

powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)

2013-08-01T03:11:47Z

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.

macintosh/windfarm: Remove obsolete cleanup for clientdata

2013-07-01T01:46:56Z

A few new i2c-drivers came into the kernel which clear the clientdata-pointer on exit or error. This is obsolete meanwhile, the core will do it. Signed-off-by: Wolfram Sang Signed-off-by: Benjamin Herrenschmidt

powerpc/windfarm: Fix overtemperature clearing

2013-07-01T01:10:34Z

With pm81/pm91/pm121, when the overtemperature state is entered, and when it remains on after skipped ticks, the driver will try to leave it too soon (immediately on the next tick). This is because the active FAILURE_OVERTEMP state is not visible in "new_failure" variable of the current tick. Furthermore, the driver will keep trying to clear condition in subsequent ticks as FAILURE_OVERTEMP remains set in the "last_failure" variable. These will start to trigger WARNINGS from windfarm core: [ 100.082735] windfarm: Clamping CPU frequency to minimum ! [ 100.108132] windfarm: Overtemp condition detected ! [ 101.952908] windfarm: Overtemp condition cleared ! [...] [ 102.980388] WARNING: at drivers/macintosh/windfarm_core.c:463 [...] [ 103.982227] WARNING: at drivers/macintosh/windfarm_core.c:463 [...] [ 105.030494] WARNING: at drivers/macintosh/windfarm_core.c:463 [...] [ 105.973666] WARNING: at drivers/macintosh/windfarm_core.c:463 [...] [ 106.977913] WARNING: at drivers/macintosh/windfarm_core.c:463 Fix by adding a helper global variable. We leave the overtemp state only after all failure bits have been cleared. I saw this error on iMac G5 iSight (pm121). Also pm81/pm91 are fixed based on the observation that these are almost identical/copy-pasted code. Signed-off-by: Aaro Koskinen Signed-off-by: Benjamin Herrenschmidt
