thermal: cpu_cooling: implement the power cooling device API

2015-05-05T04:27:52Z

Add a basic power model to the cpu cooling device to implement the power cooling device API. The power model uses the current frequency, current load and OPPs for the power calculations. The cpus must have registered their OPPs using the OPP library.

thermal: cpu_cooling: return ERR_PTR() for !CPU_THERMAL or !THERMAL_OF

2014-12-17T13:00:04Z

The documentation of of_cpufreq_cooling_register() and cpufreq_cooling_register() say that they return ERR_PTR() on error. Accordingly, callers only check for IS_ERR(). Therefore, make them return ERR_PTR(-ENOSYS) as is customary in the kernel when config options are missing.

thermal: cpu_cooling: introduce of_cpufreq_cooling_register

2013-12-04T13:33:34Z

This patch introduces an API to register cpufreq cooling device based on device tree node. The registration via device tree node differs from normal registration due to the fact that it is needed to fill the device_node structure in order to be able to match the cooling devices with trip points.

thermal: cpu_cooling: fix stub function

2013-07-08T14:13:40Z

The function stub for cpufreq_cooling_get_level introduced in 57df81069 "Thermal: exynos: fix cooling state translation" is not syntactically correct C and needs to be fixed to avoid this error: In file included from drivers/thermal/db8500_thermal.c:20:0: include/linux/cpu_cooling.h: In function 'cpufreq_cooling_get_level': include/linux/cpu_cooling.h:57:1: error: parameter name omitted unsigned long cpufreq_cooling_get_level(unsigned int, unsigned int) ^ include/linux/cpu_cooling.h:57:1: error: parameter name omitted Signed-off-by: Arnd Bergmann Acked-by: Eduardo Valentin Cc: Zhang Rui Cc: Amit Daniel kachhap Cc: stable@vger.kernel.org Signed-off-by: Eduardo Valentin

thermal: cpu cooling: allow module builds

2012-11-22T07:59:52Z

As thermal drivers can be built as modules and also the thermal framework itself, building cpu cooling only as built-in can cause linking errors. For instance: * Generic Thermal sysfs driver * Generic Thermal sysfs driver (THERMAL) [M/n/y/?] m generic cpu cooling support (CPU_THERMAL) [N/y/?] (NEW) y with the following drive: CONFIG_OMAP_BANDGAP=m generates: ERROR: "cpufreq_cooling_unregister" [drivers/staging/omap-thermal/omap-thermal.ko] undefined! ERROR: "cpufreq_cooling_register" [drivers/staging/omap-thermal/omap-thermal.ko] undefined! This patch changes cpu cooling driver to allow it to be built as module.
