[RFC PATCH 0/4] ufs: set power domain performance state when scaling gears

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This is a proof-of-concept/RFC for changing the performance state
of power rails when scaling gears.

So far I added it as a parallel method to scaling clocks, thus
freq-table-hz stays in DTS, however OPP table should be probably
replace freq-table-hz entirely.

Best regards,
Krzysztof

  dt-bindings: clock: qcom,gcc-sdm845: add parent power domain
  dt-bindings: ufs: common: allow OPP table
  arm64: dts: qcom: sdm845: control RPMHPD performance states with UFS
