[PATCH v1 08/10] arm64: dts: qcom: qrb4210-rb2: enable wsa881x amplifier

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



One WSA881X amplifier is connected on QRB4210 RB2 board
hence only mono speaker is supported. This amplifier is set
to work in analog mode only. Also add required powerdown
pins/gpios.
