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

2015-08-03T02:36:57+00:00

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

2015-08-03T02:36:57+00:00

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

2015-08-03T02:36:57+00:00

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.

thermal: exynos: Add the support for Exynos5433 TMU

2015-05-05T04:27:55+00:00

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

thermal: exynos: Fix wrong control of power down detection mode for Exynos7

2015-03-02T09:04:51+00:00

This patch fixes the wrong control of PD_DET_EN (power down detection mode) for Exynos7 because exynos7_tmu_control() always enables the power down detection mode regardless 'on' parameter.

thermal: exynos: Clean-up code to use oneline entry for exynos compatible table

2015-02-24T19:00:00+00:00

thermal: exynos: fix: Check if data->tmu_read callback is present before read

2015-02-20T13:57:02+00:00

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

thermal: exynos: Add TMU support for Exynos7 SoC

2015-01-31T19:20:45+00:00

Add registers, bit fields and compatible strings for Exynos7 TMU (Thermal Management Unit). Following are a few of the differences in the Exynos7 TMU from earlier SoCs: - 8 trigger levels - Different bit offsets and more registers for the rising and falling thresholds. - New power down detection bit in the TMU_CONTROL register which does not update the CURRENT_TEMP0 when tmu power down is detected. - Change in bit offset for the NEXT_DATA field of EMUL_CON register. EMUL_CON register address has also changed. - INTSTAT and INTCLEAR registers present in earlier SoCs have been combined into one INTPEND register. The register address for INTCLEAR and INTPEND is also different. - Since there are 8 rising/falling interrupts as against at most 4 in earlier SoCs the INTEN bit offsets are different. - Multiple probe support which is handled by a TMU_CONTROL1 register (No support for this in the current patch). This patch adds special clock support required only for Exynos7. It also updates the "code_to_temp" prototype as Exynos7 has 9 bit code-temp mapping.

thermal: exynos: Correct sanity check at exynos_report_trigger() function

2015-01-28T05:29:02+00:00

Up till now, by mistake, wrong variable was tested against being NULL. Since exynos_report_trigger() is always called with valid p pointer, it is only necessary to check if a valid thermal zone device is passed.

thermal: Kconfig: Remove config for not used EXYNOS_THERMAL_CORE

2015-01-27T14:54:56+00:00

After removing exynos_thermal_common.[c|h] files the CONFIG_EXYNOS_THERMA_CORE is not needed anymore. This patch removes this entry from Kconfig. Reported-by: Paul Bolle Signed-off-by: Lukasz Majewski Signed-off-by: Eduardo Valentin
