This series adds runtime PM support to Tegra drivers and enables core voltage scaling for Tegra20/30 SoCs, resolving overheating troubles.
All patches in this series are interdependent and should go via Tegra tree for simplicity.
Changelog:
v14: - Fixed missing runtime PM syncing on removal of drivers, which was spotted by Ulf Hansson in v13.
- clk-device driver now resumes RPM on system suspend instead of preparing clock which it backs. This was suggested by Ulf Hansson. - clk-device driver now syncs power domain performance unconditionally during driver's probe time since GENPD API allows to do this now. It was spotted by Ulf Hansson. - Added new "Enable runtime PM during OPP state-syncing" patch, which allows drivers to sync state at any time. Previously drivers were obligated to take care of enabling RPM at the "right" time. - Moved runtime PM initialization/uninitialization of DRM drivers that use host1x channel to host1x client init/deinit phase. I noticed that there is UAF problem because RPM-suspend callback waits until channel is idling and channel is already released/freed during driver's removal phase. - Added system suspend support to the new NVDEC DRM driver. - Added missing pm_runtime_mark_last_busy() to DRM driver. - Corrected VDE GENPD patch which previously made video decoder clock always-enabled by mistake if legacy PD code path was used. It was spotted while we were testing VDE on Tegra114 that doesn't support GENPD yet. - Added ack from Peter Chen to the USB patch that he gave to v13. - Changed OPP table names in accordance to the new naming scheme required by the recent core OPP binding. - Added 500MHz memory OPP entry used by ASUS Transformer tablets.Besides those minor nitpicks/questions that I have sent for patch1 and patch29, the series looks good to me!
Feel free to add, for the whole series:

Thank you, Ulf!
I'll wait for more comments and re-spin v15 with minor improvements around the end of the upcoming merge window.
