Subject: [PATCH v4 1/3] arm64: dts: qcom: sc7280: Add nodes for va tx and rx macros and external codecs
Date:   Fri, 11 Feb 2022 20:27:16 +0530

SC7280 has VA, TX and RX macros with SoundWire Controllers to attach with
codecs like WCD938x, max98360a using soundwire masters and i2s bus.
Add these nodes for sc7280 based platforms audio use case.
Add tlmm gpio property in wcd938x node for switching CTIA/OMTP Headset.
