* [PATCH] powerpc: windfarm shall request it's sub modulesBenjamin Herrenschmidt2006-11-151-0/+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.

* [POWERPC] Fix windfarm platform device usageBenjamin Herrenschmidt2006-10-101-14/+10
| | | | | | | | | The windfarm code uses a struct device_driver instead of platform_driver, which can cause crashes if any of the callbacks are called (like on module removal). This fixes it.

* [POWERPC] powermac: Constify & voidify get_property()Jeremy Kerr2006-07-311-1/+1
| | | | | | | | | | | | | Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powermac platform & macintosh driver changes.

* [PATCH] powerpc: Thermal control for dual core G5sBenjamin Herrenschmidt2006-02-071-81/+14
| | | | | | | | | | | | | 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.

* [PATCH] ppc64: Thermal control for SMU based machinesBenjamin Herrenschmidt2005-11-081-0/+814
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.
