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 Krzysztof Kozlowski (4): 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 ufs: set power domain performance state when scaling gears .../bindings/clock/qcom,gcc-sdm845.yaml | 3 ++ .../devicetree/bindings/ufs/ufs-common.yaml | 4 ++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 17 +++++++- drivers/scsi/ufs/ufshcd-pltfrm.c | 6 +++ drivers/scsi/ufs/ufshcd.c | 42 +++++++++++++++---- drivers/scsi/ufs/ufshcd.h | 3 ++ 6 files changed, 65 insertions(+), 10 deletions(-)
