2014-12-08thermal: of: Extend current of-thermal.c code to allow setting emulated tempLukasz Majewski2-0/+27
Before this change it was only possible to set get_temp() and get_trend() methods to be used in the common code handling passing parameters via device tree to "cpu-thermal" CPU thermal zone device. Now it is possible to also set emulated value of temperature for debug purposes.

2014-12-08thermal: of: Extend of-thermal to export table of trip pointsLukasz Majewski2-0/+29
This patch extends the of-thermal.c to export trip points for a given thermal zone. Thermal drivers should use of_thermal_get_trip_points() method to get pointer to table of thermal trip points.

Thermal is TS-ADC Controller module supports user-defined mode and automatic mode. User-defined mode refers,TSADC all the control signals entirely by software writing to register for direct control. Automaic mode refers to the module automatically poll TSADC output, and the results were checked.If you find that the temperature High in a period of time,an interrupt is generated to the processor down-measures taken;If the temperature over a period of time High, the resulting TSHUT gave CRU module,let it reset the entire chip, or via GPIO give PMIC.

There is no longer need to share defines between exynos_tmu.c and exynos_tmu_data.c (as they are now only used by the former file) so move them accordingly. Then move externs for struct exynos_tmu_init_data instances to exynos_tmu.h and remove no longer needed exynos_tmu_data.h include. There should be no functional changes caused by this patch.

2014-11-20thermal: exynos: remove SoC type ifdefsBartlomiej Zolnierkiewicz3-67/+8
Maximum theoretical size saving (i.e. with only Exynos5410 SoC support enabled in kernel config so all SoC dependend Exynos thermal driver code was dropped) is 4096 bytes so there is no much sense in keeping these ifdefs (especially given that they are useless once the driver gets updated to use device tree). While at it remove needless 'void *' casts. There should be no functional changes caused by this patch.

2014-11-20thermal: of: improve of-thermal sensor registration APIEduardo Valentin7-37/+62
Different drivers request API extensions in of-thermal. For this reason, additional callbacks are required to fit the new drivers needs. The current API implementation expects the registering sensor driver to provide a get_temp and get_trend callbacks as function parameters. As the amount of callbacks is growing, this patch changes the existing implementation to use a .ops field to hold all the of thermal callbacks to sensor drivers. This patch also changes the existing of-thermal users to fit the new API design. No functional change is introduced in this patch.

2014-11-20thermal: introduce clock cooling deviceEduardo Valentin4-0/+565
This patch introduces a new thermal cooling device based on common clock framework. The original motivation to write this cooling device is to be able to cool down thermal zones using clocks that feed co-processors, such as GPUs, DSPs, Image Processing Co-processors, etc. But it is written in a way that it can be used on top of any clock. The implementation is pretty straight forward. The code creates a thermal cooling device based on a pair of a struct device and a clock name. The struct device is assumed to be usable by the OPP layer. The OPP layer is used as source of the list of possible frequencies. The (cpufreq) frequency table is then used as a map from frequencies to cooling states. Cooling states are indexes to the frequency table. The logic sits on top of common clock framework, specifically on clock pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is only allowed when the new rate is within the thermal limit (cooling state -> freq). When a thermal cooling device state transition is requested, the clock is also checked to verify if the current clock rate is within the new thermal limit.
