[PATCH v11 00/34] NVIDIA Tegra power management patches for 5.16

[Dmitry Osipenko]

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.

Changelog:

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.
