Subject: [PATCH v13 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:
v13: - Fixed compile-test error reported by build bot by reverting the
mmc/ patch to v11. The sdhci_suspend/resume_host() functions aren't
available with the disabled CONFIG_PM_SLEEP, some code needs the
ifdef.
- Added last r-b from Rob Herring for the DT patches.
- Corrected clk/ PM domain-support patch by not using the
devm_tegra_core_dev_init_opp_table_common() helper, which I
utilized in v12. The clk driver implements its own power domain
state syncing and common helper shouldn't be used. This fixes driver
probing for some clocks on some devices. It was reported by
Svyatoslav Ryhel for PLLE OPP error on T30 Asus Transformer tablet.
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.
