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.

Please note that this series is made on top of ACMTON patches! [1].
Otherwise tegra30.dtsi will fail to compile.

Changelog:

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.
