[v8,00/34] NVIDIA Tegra power management patches for 5.16

Message

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.
