2008-04-24[POWERPC] macintosh/windfarm: Fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable "macintosh" platform drivers, to re-enable auto loading.

2006-11-15[PATCH] powerpc: windfarm shall request it's sub modulesBenjamin Herrenschmidt
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 Herrenschmidt
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. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-03[PATCH] powerpc: Fix windfarm_pm112 not starting all control loopsBenjamin Herrenschmidt
This adds a couple of printk's to windfarm_pm112 to display which control loops are actually starting and fixes a bug where it would not start all loops. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-03[PATCH] powerpc: Fix old g5 issues with windfarmBenjamin Herrenschmidt
Some of the windfarm sensor modules can initialize on old machines that don't have full windfarm support like non-dual core desktop G5s. Unfortunately, by doing so, they would trigger a bug in their matching algorithm causing them to attach to the wrong bus, thus triggering issues with the i2c core and breaking the thermal driver. This patch fixes the probing issue (so that they will work when a windfarm port is done to these machines) and also prevents for now windfarm to load at all on these machines that still use therm_pm72 to avoid wasting resources.

2006-02-07[PATCH] powerpc: Thermal control for dual core G5sBenjamin Herrenschmidt
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.
