Subject: [PATCH v12 00/35] NVIDIA Tegra power management patches for 5.16
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:
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.
