2019-06-19treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 246Thomas Gleixner1-3/+1
Based on 1 normalized pattern(s): released under the term of the gnu gpl v2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 16 file(s).

2013-07-01powerpc/windfarm: Fix overtemperature clearingAaro Koskinen1-1/+5
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 !

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.

2013-01-03Drivers: macintosh: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
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.

2006-11-15[PATCH] powerpc: windfarm shall request it's sub modulesBenjamin Herrenschmidt1-0/+1
The windfarm code, in it's current incarnation, uses request_module() to load the various submodules it needs for a given platform so that only the main platform control module needs to be modprobed. However, it was missing various bits. This fixes it. In the future, we'll use some hotplug mecanisms to try to get all of this auto-loaded on the platforms where it matters but that isn't ready yet.

2006-10-10[POWERPC] Fix windfarm platform device usageBenjamin Herrenschmidt1-14/+10

2006-02-07[PATCH] powerpc: Thermal control for dual core G5sBenjamin Herrenschmidt1-75/+12
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.

2005-11-08[PATCH] ppc64: Thermal control for SMU based machinesBenjamin Herrenschmidt1-0/+879
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.
