Subject: [PATCH V4 00/16] Add generic PM domain support for Tegra

Adds generic PM domain support for Tegra SoCs but so far it is only
enabled Tegra 64-bit devices. There is no reason why this cannot be
enabled for Tegra 32-bit devices, but to keep the patch series to a
minimum only 64-bit devices are enabled.

This series has been boot tested on Tegra210 as well as various 32-bit
Tegra platforms.

Summary of changes since V3 [0]:
- Dropped tegra124 support for now
- Removed MC flush support per feedback from Thierry
- Cleaned up the PMC changes per feedback from Thierry
- Added support for tegra210

Series Summary:
Patch 1:    Adds the new function of_reset_control_get_by_index().
Patch 2-9:  PMC clean-up and fixes
Patch 10:   Adds function to remove a generic PM domain
Patch 11:   Updates DT documentation for PMC w.r.t Tegra210
Patch 12:   Adds DT documentation for tegra generic PM domains
Patch 13:   Adds PMC generic DM domains support
Patch 14:   Adds audio clock for Tegra210 audio power-domain
Patch 15:   Adds DT bindings for Tegra210 audio power-domain
Patch 16:   Enable generic PM domains for tegra64
