This series adds runtime PM support to Tegra drivers and enables core voltage scaling for Tegra20/30 SoCs, resolving overheating troubles.
All patches should go via Tegra tree because they are interdependent, please review and ack.
If you haven't seen this series before, that's because I wanted to finalize the GENPD part at first and didn't bother you previously.
Changelog:
v8: - Added new generic dev_pm_opp_sync() helper that syncs OPP state with hardware. All drivers changed to use it. This replaces GENPD attach_dev callback hacks that were used in v7.
- Added new patch patch "soc/tegra: regulators: Prepare for suspend" that fixes dying Tegra20 SoC after enabling VENC power domain during resume from suspend. It matches to what downstream kernel does on suspend/resume.
- After a second thought, I dropped patches which added RPM to memory drivers since hardware is always-on and RPM not needed.
- Replaced the "dummy host1x driver" patch with new "Disable unused host1x hardware" patch, since it's a cleaner solution.
