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

From: Nikita Travkin
Date: Thu Apr 06 2023 - 11:07:26 EST


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.
