Subject: [PATCH v2 1/3] arm64: dts: qcom: sc8280xp-crd: model the PMU of the on-board wcn6855
From: Konrad Dybcio <konradybcio@...nel.org>
Add nodes for the WCN6855 PMU, the WLAN module and relevant regulators
and pin functions to fully describe how the wifi is actually wired on
this platform.
Signed-off-by: Konrad Dybcio <konradybcio@...nel.org>
