[PATCH v3 00/17] DVFS for IO devices on sdm845 and sc7180

From: Rajendra Nayak
Date: Tue Apr 28 2020 - 09:38:44 EST


Changes in v3:
1. Added better error handling for dev_pm_opp_of_add_table()
2. Some minor changes and fixes in PATCH 12/17 as compared to v2
3. Dropped the mmc patch since its picked up by Ulf

1. Added error handling for dev_pm_opp_set_clkname()
and dev_pm_opp_of_add_table()
2. Used dev_pm_opp_put_clkname() in the cleanup path
3. Dropped the OPP patch pulled in by Viresh [1]
4. Dropped the UFS patches since they had some major rework
needed because of changes that were merged in the merge window
and I don't have a UFS device currently to validate the changes.

We have had support added in the OPP core for a while now to support
DVFS for IO devices, and this series uses that infrastructure to
add DVFS support for various IO devices in sdm845 and sc7180 SoCs.
