[PATCH v5 1/3] arm64: dts: qcom: sc8280xp-crd: model the PMU of the on-board wcn6855

From: Bartosz Golaszewski
Date: Tue Oct 08 2024 - 06:26:14 EST


From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

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.
