[PATCH v4 0/6] Add driver for NVIDIA Tegra30 SoC Thermal sensor

[Dmitry Osipenko]

Hi,

This series adds support for the thermal sensor that is found on NVIDIA
Tegra30 SoC. Sensor monitors temperature and voltage of the SoC, it also
emits signals to the power management and clock controllers that are
performing the emergency shut down and the CPU frequency throttling
when a pre-programmed temperature levels are reached.

Changelog:

v4: - Removed DIV2 CPU frequency throttling and cooling device part as was
      suggested by Daniel Lezcano since we need to notify cpufreq about the
      updated frequency and change the thermal pressure. The thermal pressure
      change should co-exists with the cpufreq_cooling. This all needs some
      more thought, so the DIV2 mitigation will come sometime later.

    - Added ack from Thierry Reding.

    - Changed default TZ trips in the device-tree to the silicon temperature
      levels, instead of the average device levels.

v3: - No code changes. CC'ed linux-pm, which was previously missed by accident.
      Not sure how much that is important for the thermal patches, but won't
      hurt to re-send since only DT binding was reviewed so far.

v2: - Made a very minor improvement to one error message, it now prints
      number of channel at which error occurred.

    - Added r-b from Rob Herring to the binding.
