Subject[RESEND PATCH v2 0/7] clk: qcom: use power-domain for sm8250's clock controllers
Date

On SM8250 both the display and video clock controllers are powered up by
the MMCX power domain. Handle this by linking clock controllers to the
proper power domain, and using runtime power management to enable and
disable the MMCX power domain.

Dependencies:
- https://lore.kernel.org/linux-pm/20210603093438.138705-1-ulf.hansson@linaro.org/ (merged in 5.14)
- https://lore.kernel.org/linux-arm-msm/20210703005416.2668319-1-bjorn.andersson@linaro.org/
(pending)

Patches resent because I missed one hunk in the PM domains patch, which
got stuck in the git index. Now the patch is fixed.

Changes since v1:
- Rebase on top of Bjorn's patches, removing the need for setting
performance state directly.
- Move runtime PM calls from GDSC code to generic genpd code.
- Always call pm_runtime_enable in the Qualcomm generic clock
controller code.
- Register GDSC power domains as subdomains of the domain powering the
clock controller if there is one.
