Subject: [RFC 2/9] arm64: dts: qcom: qrb5165-rb5: model the PMU of the QCA6391
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
Add a node for the PMU module of the QCA6391 present on the RB5 board.
Assign its LDO power outputs to the existing Bluetooth module. Add a
node for the PCIe port to sm8250.dtsi and define the WLAN node on it in
the board's .dts and also make it consume the power outputs of the PMU.
