[PATCH v4 0/6] clk: qcom: use power-domain for sm8250's clock controllers
From: Dmitry Baryshkov
Date: Fri Jul 09 2021 - 21:34:06 EST
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@xxxxxxxxxx/ (merged in 5.14)
- https://lore.kernel.org/linux-arm-msm/20210703005416.2668319-1-bjorn.andersson@xxxxxxxxxx/
(pending)
Changes since v3:
- Wrap gdsc_enable/gdsc_disable into pm_runtime_get/put calls rather
than calling pm_runtime_get in gdsc_enabled and _put in gdsc_disable
- Squash gdsc patches together to remove possible dependencies between
two patches.
Changes since v2:
- Move pm_runtime calls from generic genpd code to the gdsc code for
now (as suggested by Ulf & Bjorn)
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.
