Merge tag 'for-v3.6' of git://git.infradead.org/battery-2.6

2012-08-01T01:08:25Z

Pull battery updates from Anton Vorontsov: "The tag contains just a few battery-related changes for v3.6. It's is all pretty straightforward, except one thing. One of our patches added thermal support for power supply class, but thermal/ subsystem changed under our feet. We (well, Stephen, that is) caught the issue and it was decided[1] that I'd just delay the battery pull request, and then will fix it up by merging upstream back into battery tree at the specific commit. That's not all though: another[2] small fixup for thermal subsystem was needed to get rid of a warning in power supply subsystem (the warning was not drivers/power's "fault", the thermal registration function just needed a proper const annotation, which is also done by a small commit on top of the merge. So, to sum this up: - The 'master' branch of the battery tree was in the -next tree for weeks, was never rebased, altered etc. It should be all OK; - Although, for-v3.6 tag contains the 'master' branch + merge + the warning fix.

thermal: Constify 'type' argument for the registration routine

2012-07-31T12:45:37Z

thermal_zone_device_register() does not modify 'type' argument, so it is safe to declare it as const. Otherwise, if we pass a const string, we are getting the ugly warning: CC drivers/power/power_supply_core.o drivers/power/power_supply_core.c: In function 'psy_register_thermal': drivers/power/power_supply_core.c:204:6: warning: passing argument 1 of 'thermal_zone_device_register' discards 'const' qualifier from pointer target type [enabled by default] include/linux/thermal.h:140:29: note: expected 'char *' but argument is of type 'const char *' Signed-off-by: Anton Vorontsov Acked-by: Jean Delvare

Thermal: Add Hysteresis attributes

2012-07-25T03:19:26Z

The Linux Thermal Framework does not support hysteresis attributes. Most thermal sensors, today, have a hysteresis value associated with trip points. This patch adds hysteresis attributes on a per-trip-point basis, to the Thermal Framework. These attributes are optionally writable.

Thermal: Make Thermal trip points writeable

2012-07-25T03:17:20Z

Some of the thermal drivers using the Generic Thermal Framework require (all/some) trip points to be writeable. This patch makes the trip point temperatures writeable on a per-trip point basis, and modifies the required function call in thermal.c. This patch also updates the Documentation to reflect the new change. Signed-off-by: Durgadoss R Signed-off-by: Zhang Rui Signed-off-by: Len Brown

drivers/thermal/spear_thermal.c: add Device Tree probing capability

2012-06-02T05:49:38Z

SPEAr platforms now support DT and so must convert all drivers to support DT. This patch adds DT probing support for SPEAr thermal sensor driver and updates its documentation too. Also, as SPEAr is the only user of this driver and is only available with DT, make this an only DT driver. So, platform_data is completely removed and passed via DT now.

thermal: Fix for setting the thermal zone mode to enable/disable

2012-03-22T05:10:18Z

Basically without this patch changing the mode of thermal zone is not possible as wrong string size is passed to strncmp. Signed-off-by: Amit Daniel Kachhap Acked-by: Jean Delvare Signed-off-by: Len Brown

thermal: spear13xx: checking for NULL instead of IS_ERR()

thermal/spear_thermal: replace readl/writel with lighter _relaxed variants

2012-03-22T05:06:43Z

readl/writel versions for ARM contain memory barrier instruction for synchronizing DMA buffers. These are not required at least on this module. So use lighter _relaxed variants. Signed-off-by: Viresh Kumar Signed-off-by: Andrew Morton Signed-off-by: Len Brown

thermal: add support for thermal sensor present on SPEAr13xx machines

2012-03-22T05:05:32Z

ST's SPEAr13xx machines are based on CortexA9 ARM processors. These machines contain a thermal sensor for junction temperature monitoring. This patch adds support for this thermal sensor in existing thermal framework.
