[PATCH] arm64: dts: qcom: qcs6490-rb3gen2: Enable PWR/VOL keys
From: Bjorn Andersson
Date: Fri Oct 04 2024 - 22:44:23 EST
From: Konrad Dybcio <quic_kdybcio@xxxxxxxxxxx>
RB3Gen2 has three tiny buttons located under the blue USB-A ports.
They're all connected through the various PMICs and are used for
volume and power.
Describe them.
