This series adds resource-managed OPP API helpers and makes drivers to use them.
Changelog:
v3: - Dropped dev_pm_opp_register_notifier().
- Changed return type of the devm helpers from opp_table pointer to errno.
- Corrected drm/msm patch which missed to remove opp_put_supported_hw() from a6xx_gpu. Note that the a5xx_gpu driver was missing the opp_put_supported_hw() at all.
- Corrected spelling of the ack from Mark Brown.
v2: - This is a continuation of the work that was started by Yangtao Li. Apparently Yangtao doesn't have time to finish it, so I (Dmitry Osipenko) picked up the effort since these patches are wanted by the NVIDIA Tegra voltage-scaling series that I'm working on.
- Fixed the double put of OPP resources.
- Dropped all patches that are unrelated to OPP API. I also dropped the Tegra memory patch since it doesn't apply now and because I plan to switch all Tegra drivers soon to a common tegra-specific OPP helper that will use the resource-managed OPP API anyways.
- Squashed couple patches into a single ones since there was no good reason to separate them.
- Added acks that were given to a couple of v1 patches.

I'll take this through media-tree once OPP API changes are merged.

This series adds resource-managed OPP API helpers and makes drivers to use them.
Changelog:
v3: - Dropped dev_pm_opp_register_notifier().
- Changed return type of the devm helpers from opp_table pointer to errno. - Corrected drm/msm patch which missed to remove opp_put_supported_hw() from a6xx_gpu. Note that the a5xx_gpu driver was missing the opp_put_supported_hw() at all. - Corrected spelling of the ack from Mark Brown.
Applied all patches except 11/15.
Thanks.
