[PATCH v1 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.
