| * thermal: ti-soc-thermal: OMAP5: Implement Workaround for Errata i813Keerthy2015-05-083-3/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DESCRIPTION Spurious Thermal Alert: Talert can happen randomly while the device remains under the temperature limit defined for this event to trig. This spurious event is caused by a incorrect re-synchronization between clock domains. The comparison between configured threshold and current temperature value can happen while the value is transitioning (metastable), thus causing inappropriate event generation. No spurious event occurs as long as the threshold value stays unchanged. Spurious event can be generated while a thermal alert threshold is modified in CONTROL_BANDGAP_THRESHOLD_MPU/GPU/CORE/DSPEVE/IVA_n. WORKAROUND Spurious event generation can be avoided by performing following sequence when the threshold is modified: 1. Mask the hot/cold events at the thermal IP level. 2. Modify Threshold. 3. Unmask the hot/cold events at the thermal IP level. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>

Read access to registers below can be corrupted : • CTRL_CORE_DTEMP_MPU/GPU/CORE/DSPEVE/IVA_n (n = 0 to 4) • CTRL_CORE_TEMP_SENSOR_MPU/GPU/CORE/DSPEVE/IVA_n WORKAROUND Multiple reads to CTRL_CORE_TEMP_SENSOR_MPU/GPU/CORE/DSPEVE/IVA[9:0]: BGAP_DTEMPMPU/GPU/CORE/DSPEVE/IVA is needed to discard false value and read right value: 1. Perform two successive reads to BGAP_DTEMP bit field. (a) If read1 returns Val1 and read2 returns Val1, then right value is Val1. (b) If read1 returns Val1, read 2 returns Val2, a third read is needed. 2. Perform third read (a) If read3 returns Val2 then right value is Val2. (b) If read3 returns Val3, then right value is Val3. The above in gist means if val1 and val2 are the same then we can go ahead with that value else we need a third read which will be right since synchronization will be complete by then.

| * thermal: exynos: Add TMU support for Exynos7 SoCAbhilash Kesavan2015-01-312-8/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added thermal zones for processor thermal using APIs provided by int340x thermal zone module. Like other INT340x devices, processor thermal device can also contain trip points and way to get temperature. On some platform there is no ACPI _TMP method, in those platform using IA64 architecture MSRs to get temperature.

| | * | Thermal/int340x: Add common thermal zone handlerSrinivas Pandruvada2015-01-203-0/+328
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the processing for each int340x driver to add a thermal zone is very similar and every driver has to duplicate code. Created a common module, which exports API to add and remove zones. In this way, we not only avoid duplicate code but also helps in bug fixes and enhancements. If for some driver default processing for thermal zone callback is not enough they can overide individual callback. The code for this driver is primarily copied from int3402_thermal.c.
