Subject: [PATCH v2 00/13] NVIDIA Tegra ARM32 device-tree improvements

Hi,

This series is partially factored out from [1] since the DT patches
could be applied separately. In addition I added couple more new
patches and implemented suggestion given by Daniel Lezcano to [1],
see "Specify all CPU cores as cooling devices" patches.

[1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=221130

Please note that this patchset enables voltage scaling for a few boards,
but currently voltage scaling is limited in kernel by the regulator coupler
drivers, so it's safe to change the device-trees. Voltage scaling will
be fully unlocked once [1] will be merged.

Changelog:

v2: - The "acer-a500: Rename avdd to vdda of touchscreen node" patch
      now shouldn't have merge conflicts with the upstream kernel since
      v1 was based on a patch that adds a new atmel,wakeup-method property,
      which is not supported by upstream yet.

    - Fixed unwrapped commit description in the "cardhu: Support CPU
      frequency and voltage" patch.
