This series adds runtime PM support to Tegra drivers and enables core
voltage scaling for Tegra20/30 SoCs, resolving overheating troubles.

All patches in this series are interdependent and should go via Tegra tree.

Changelog:

v13: - Fixed compile-test error reported by build bot by reverting the
       mmc/ patch to v11. The sdhci_suspend/resume_host() functions aren't
       available with the disabled CONFIG_PM_SLEEP, some code needs the
       ifdef.

     - Added last r-b from Rob Herring for the DT patches.

     - Corrected clk/ PM domain-support patch by not using the
       devm_tegra_core_dev_init_opp_table_common() helper, which I
       utilized in v12. The clk driver implements its own power domain
       state syncing and common helper shouldn't be used. This fixes driver
       probing for some clocks on some devices. It was reported by
       Svyatoslav Ryhel for PLLE OPP error on T30 Asus Transformer tablet.
Dmitry, I have looked through the series and besides those comments
that I have posted, I have nothing more to add. Overall it looks good
to me.

Kind regards
Uffe
