2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-02-09of: add 'of_' prefix to machine_is_compatible()Grant Likely
machine is compatible is an OF-specific call. It should have the of_ prefix to protect the global namespace. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>
2009-10-04macintosh: Don't assume i2c device probing always succeedsJean Delvare
If i2c device probing fails, then there is no driver to dereference after calling i2c_new_device(). Stop assuming that probing will always succeed, to avoid NULL pointer dereferences. We have an easier access to the driver anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Tim Shepard <shep@alum.mit.edu> Cc: Colin Leroy <colin@colino.net>

The legacy i2c binding model is going away soon, so convert the macintosh windfarm drivers to the new model or they will break.

2008-04-29[POWERPC] windfarm: Add PowerMac 12,1 supportÉtienne Bersac
This implements a new driver named windfarm_pm121, which drives the fans on PowerMac 12,1 machines : iMac G5 iSight (rev C) 17" and 20". It's based on the windfarm_pm81 driver from Benjamin Herrenschmidt. This includes fixes from David Woodhouse correcting the names of some of the sensors.

for consistency with other Open Firmware interfaces (and Sparc). This is just a straight replacement. This leaves the compatibility define in place. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> 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.
