2015-01-24thermal: exynos: Provide thermal_exynos.h file to be included in device tree ↵Lukasz Majewski1-0/+28
files This patch is a preparatory patch to be able to read Exynos thermal configuration from the device tree. It turned out that DTC is not able to interpret enums properly and hence it is necessary to #define those values explicitly. For this reason the ./include/dt-bindings/thermal/thermal_exynos.h file has been introduced.

2014-12-10thermal: Fix cdev registration with THERMAL_NO_LIMIT on 64bitPunit Agrawal1-1/+1
The size of unsigned long varies between 32 and 64 bit systems while the size of phandle arguments is always 32 bits per parameter. On 64-bit systems, cooling devices registered via of-thermal apis fail to bind when the min/max cooling state is specified as THERMAL_NO_LIMIT (-1UL) as there is a mis-match between the value read from the device tree (32bit) and the pre-processor define (64bit). As we're unlikely to need cooling states larger than 32 bits, and for consistency with the size of phandle arguments, explicitly limit THERMAL_NO_LIMIT to 32 bits.

2013-12-04thermal: introduce device tree parserEduardo Valentin1-0/+17
This patch introduces a device tree bindings for describing the hardware thermal behavior and limits. Also a parser to read and interpret the data and feed it in the thermal framework is presented. This patch introduces a thermal data parser for device tree. The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.
