thermal: exynos: Disable the regulator on probe failure

2015-08-17T03:52:25Z

commit 5f09a5cbd14ae16e93866040fa44d930ff885650 upstream. 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: Fix wrong control of power down detection mode for Exynos7

2015-03-02T09:04:51Z

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

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

thermal: exynos: Add TMU support for Exynos7 SoC

2015-01-31T19:20:45Z

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

2015-01-28T05:29:02Z

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: samsung: core: Exynos TMU rework to use device tree for configuration

2015-01-24T21:39:32Z

This patch brings support for providing configuration via device tree. Previously this data has been hardcoded in the exynos_tmu_data.c file. Such approach was not scalable and very often required copying the whole data. Signed-off-by: Lukasz Majewski Signed-off-by: Eduardo Valentin
