Subject: [PATCH v2 3/8] ASoC: dt-bindings: wcd937x-sdw: add bindings for wcd937x-sdw

From: Prasad Kumpatla <quic_pkumpatl@...cinc.com>

Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices RX and
TX respectively.
This binding is for those slave devices on WCD9370/WCD9375.
