Every SoundWire slave device is +uniquely determined by the enumeration address containing 5 fields: +SoundWire Version, Instance ID, Manufacturer ID, Part ID and Class ID +for a device. Addition to below required properties, child nodes can +have device specific bindings. + +Required property for SoundWire child node if it is present: +- compatible: "sdwVER,MFD,PID,CID". The textual representation of + SoundWire Enumeration address comprising SoundWire + Version, Manufacturer ID, Part ID and Class ID, + shall be in lower-case hexadecimal with leading + zeroes suppressed. + Version number '0x10' represents SoundWire 1.0 + Version number '0x11' represents SoundWire 1.1 + ex: "sdw10,0217,2010,0" + +- sdw-instance-id: Should be ('Instance ID') from SoundWire + Enumeration Address. Instance ID is for the cases + where multiple Devices of the same type or Class + are attached to the bus. + +SoundWire example for Qualcomm's SoundWire controller: + +soundwire@c2d0000 { + compatible = "qcom,soundwire-v1.5.0" + reg = <0x0c2d0000 0x2000>; + + spkr_left:wsa8810-left{ + compatible = "sdw10,0217,2010,0"; + sdw-instance-id = <1>; + ... + }; + + spkr_right:wsa8810-right{ + compatible = "sdw10,0217,2010,0"; + sdw-instance-id = <2>; + ... + }; +};

This patch adds support to parsing device tree based SoundWire slave devices.

This patch adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier. This Amplifier is primarily interfaced with SoundWire. One WSA is used for mono speaker configuration and second one would give stereo setup.

This patch is tested on SDM845 based DragonBoard DB845c.
