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
