[PATCH V2 0/5] Tegra xHCI genpd support
This series add genpd support for the Tegra xHCI device that requires more than one power-domain to operate. This series is making changes to more than one subsystem and at first glance may look like a maintainers nightmare. However, my proposal is this, once reviewed and people are happy ... 1. Patches 1-3 should be merged first. Patches 1 can go via the Tegra tree and 2-3 via the USB tree. 2. Once patches 1-3 are accepted, then 4 and 5 can be merged via the Tegra tree. Changes since V1: - Dropped unneeded patch to export symbol for genpd API - Added patch to power-off XUSB domains - Slight re-work to Tegra xHCI driver changes to simplify clean-up path.
