[PATCH v4 1/4] arm64: dts: qcom: sc7180: Don't enable lpass clocks by default

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

 



lpass clocks are usually blocked from HLOS by the firmware and
instead are managed by the ADSP. Mark them as reserved and explicitly
enable in the CrOS boards that have special, cooperative firmware.
