[PATCH V3 00/19] Add generic PM domain support for Tegra SoCs

[Jon Hunter]

This series is based upon the V2 series from Vince Hsu [1]. The code
for the MC flush operations and PMC code for the generic PM domains
has been re-written to simplify and consolidate legacy/existing support
for power-domains on the Tegra SoC.

This series has been boot tested on various 32-bit Tegra platforms
as well as compile tested for 64-bit ARM. A summary of the results is
available here [2]. Would be great to get some more testing for PCI,
SATA, GR3D and DRM.

Summary:

Patch 1:     Adds the new function of_reset_control_get_by_index().
Patch 2-5:   Add the MC flush operations for Tegra30/Tegra114/Tegra124.
Patch 6:     Is a PLLD fix for Tegra114.
Patch 7-9:   PMC preparation for generic PM domains.
Patch 10-13: Update drivers to support generic PM domains
Patch 14:    Add DT documentation for tegra generic PM domains
Patch 15:    Add PMC generic DM domains support
Patch 16:    Remove legacy functions
Patch 17-18: Add DT bindings for tegra124
Patch 19:    Enable generic PM domains for tegra


Changes:
   v3:
   * Re-wrote and simplified MC flush code
   * Re-wrote PMC code for generic PM domains to permit devices to use
     legacy DT blobs without generic PM domain info.
   * Re-worked DRM, PCI, AHCI and GR3D drivers to allow then to work
     with and without generic PM domains.
   * Added DT documentation for tegra generic PM domain bindings.
   * Dropped DT bindings for T30 and T114 (plan to add later)

   v2 (Vince Hsu):
   * Add support for Tegra30/Tegra114
   * Address Alex's comments
