+ - st,iec60958: support S/PDIF IEC6958 protocol for playback
+ IEC60958 protocol is not available for capture.
+ By default, custom protocol is assumed, meaning that protocol is
+ configured according to protocol defined in related DAI link node,
+ such as i2s, left justified, right justified, dsp and pdm protocols.

The device node should contain one 'port' child node with one child 'endpoint'
node, according to the bindings defined in Documentation/devicetree/bindings/
