* thermal: exynos: Fix register read in TMUSudip Mukherjee2015-10-171-1/+1
| | | | | | | | | | | | | | 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 temperaturesSascha Hauer2015-08-031-12/+11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

So an unsuccessful probe lead to enabling the regulator which was actually not needed because the device was not enabled.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpufreq_cooling_register() expects mask of all the CPUs where frequency constraint is applicable. This platform has more than one CPU to which these constraints will apply and so passing mask of only CPU0 wouldn't be sufficient. Also, this platform has a single cluster of CPUs and the constraint applies to all CPUs. If CPU0 is hoplugged out then we may face strange BUGs as cpu_cooling framework isn't aware of any siblings sharing clock line. Fix it by passing cpu_present_mask to cpufreq_cooling_register().

| * thermal: cpu_cooling: check for the readiness of cpufreq layerEduardo Valentin2014-12-082-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this patch, the cpu_cooling code checks for the usability of cpufreq layer before proceeding with the CPU cooling device registration. The main reason is: CPU cooling device is not usable if cpufreq cannot switch frequencies. Similar checks are spread in thermal drivers. Thus, the advantage now is to have the check in a single place: cpu cooling device registration. For this reason, this patch also updates the existing drivers that depend on CPU cooling to simply propagate the error code of the cpu cooling registration call. Therefore, in case cpufreq is not ready, the thermal drivers will still return -EPROBE_DEFER, in an attempt to try again when cpufreq layer gets ready.
