Subject: [PATCH 3/5] arm64: dts: qcom: sc7180: Don't enable lpass clocks by
|
||
|
|
default
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
The IDP board gets lpass clocks disabled as it doesn't make use of sound
|
||
|
|
anyway and might use Qualcomm firmware that blocks those clocks. [1]
