All patches in this series are interdependent and should go via Tegra tree. Changelog: v12: - Added r-b from Rob Herring to the host1x binding patch. - Added acks from Hans Verkuil to the video decoder patches. - In the v11 changelog I forgot to mention that the clk-binding patch was also changed with a corrected regex pattern and removed 'clocks' sub-node. This patch needs r-b or ack too. - Added new "Rename 3d power domains" patch to match the DT schema naming requirement. Thanks to David Heidelberg for spotting this problem. - Replaced #ifdef CONFIG_PM_SLEEP with maybe_unused in the MMC patch to make code cleaner. v11: - Added acks and r-b from Rob Herring, Mark Brown and Miquel Raynal that were given to v8. - Corrected order of the new memory controller reset entry in device-trees and host1x DT binding patch, which was requested by Rob Herring. - Switched consumer drivers to use power domain state syncing done by new Tegra's common OPP-initialization helper. - Made use of new devm_pm_runtime_enable() helper that was added to v5.15 kernel, where appropriate. - Added "fuse: Use resource-managed helpers" patch. - Converted Tegra20/30 clk drivers to a proper platform drivers, which was requested by Thierry Reding. - Removed clk-bulk API usage from the MMC patch, which was requested by Thierry Reding. - Changed CORE power domain name to "core" in a new patch "Change name of core power domain". - Misc small fixes for problems that I found since v8, like couple typos in error code paths and restored working RPM for Tegra DRM UAPI v1 that was removed in v8 by accident. v9-v10: Figured out remaining GENPD API changes with Ulf Hansson and Viresh Kumar. The OPP-sync helper that was used in v8 isn't needed anymore because GENPD API now allows consumer drivers to init rpm_pstate of power domains. 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.
