2016-02-10thermal: spear: use __maybe_unused for PM functionsArnd Bergmann1-4/+2
The spear thermal driver hides its suspend/resume function conditionally based on CONFIG_PM, but references them based on CONFIG_PM_SLEEP, so we get a warning if the former is set but the latter is not: thermal/spear_thermal.c:58:12: warning: 'spear_thermal_suspend' defined but not used [-Wunused-function] thermal/spear_thermal.c:75:12: warning: 'spear_thermal_resume' defined but not used [-Wunused-function] This removes the #ifdef and instead uses a __maybe_uninitialized annotation to avoid the warning and improve compile-time coverage.

2015-08-03thermal: consistently use int for temperaturesSascha Hauer1-1/+1
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

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.

2012-06-02drivers/thermal/spear_thermal.c: add Device Tree probing capabilityViresh Kumar1-10/+16
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.
