[PATCH v3 1/4] arm64: dts: qcom: sc7180: Don't enable lpass clocks by default
From: Nikita Travkin
Date: Wed Mar 15 2023 - 11:43:54 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.
