thermal: exynos: Fix register read in TMU

2015-10-16T23:08:56Z

The value of emul_con was getting overwritten if the selected soc is SOC_ARCH_EXYNOS5260. And so as a result we were reading from the wrong register in the case of SOC_ARCH_EXYNOS5260.

thermal: consistently use int for temperatures

2015-08-03T15:15:50Z

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.

thermal: exynos: Remove unused code related to platform_data on probe()

2015-08-03T02:36:57Z

This patch removes the unused code related to struct exynos_tmu_platform_data because exynos_tmu_probe() don't handle the struct exynos_tmu_platform_data *pdata.

thermal: exynos: Add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF

2015-08-03T02:36:57Z

The exynos thermal driver use the of_thermal_*() API to parse the basic data for thermal management from devicetree file. So, if CONFIG_EXYNOS_THERMAL is selected without CONFIG_THERMAL_OF, kernel can build it without any problem. But, exynos thermal driver is not working with following error log. This patch add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF. [ 1.458644] get_th_reg: Cannot get trip points from of-thermal.c! [ 1.459096] get_th_reg: Cannot get trip points from of-thermal.c! [ 1.465211] exynos4412_tmu_initialize: No CRITICAL trip point defined at of-thermal.c!

thermal: exynos: Disable the regulator on probe failure

2015-08-03T02:36:57Z

During probe the regulator (if present) was enabled but not disabled in case of failure. So an unsuccessful probe lead to enabling the regulator which was actually not needed because the device was not enabled. Additionally each deferred probe lead to increase of regulator enable count so it would not be effectively disabled during removal of the device.

This patch adds the support for Exynos5433's TMU (Thermal Management Unit). Exynos5433 has a little different register bit fields as following description: - Support the eight trip points for rising/falling interrupt by using two registers - Read the calibration type (1-point or 2-point) and sensor id from TRIMINFO register - Use a little different register address Cc: Zhang Rui Cc: Eduardo Valentin Cc: Lukasz Majewski Signed-off-by: Chanwoo Choi Signed-off-by: Eduardo Valentin

2015-02-20T13:57:02Z

The exynos_tmu_data() function should on entrance test not only for valid data pointer, but also for data->tmu_read one. It is important, since afterwards it is dereferenced to get temperature code. Signed-off-by: Lukasz Majewski Tested-by: Abhilash Kesavan Signed-off-by: Zhang Rui
