+ <0> if only I2S or S/PDIF pin is wired,
+ <1> if both are wired.
+ HDMI audio is configured only if this property is found.
+ If HDMI audio is configured, the sii902x device becomes an I2S and/or
+ S/PDIF audio codec component (e.g. a digital audio sink), that can be
+ used in configuring full audio devices with simple-card or
+ audio-graph-card bindings. See their binding documents on how to describe
+ the way the
+ sii902x device is connected to the rest of the audio system:
+ Documentation/devicetree/bindings/sound/simple-card.yaml
+ Documentation/devicetree/bindings/sound/audio-graph-card.yaml
+ Note: In case of the audio-graph-card binding the used port index should
+ be 3.

+ Each integer indicates which I2S pin is connected to which audio FIFO.
+ The first integer selects the I2S audio pin for the first audio FIFO#0
+ (HDMI channels 1&2), the second for FIFO#1 (HDMI channels 3&4), and so
+ on. There are 4 FIFOs and 4 I2S pins (SD0 - SD3). Any I2S pin can be
+ connected to any FIFO, but there can be no gaps. E.g. an I2S pin must be
+ mapped to FIFO#0 and FIFO#1 before mapping a channel to FIFO#2. The
+ default value is <0>, describing SD0 pin being routed to HDMI audio
+ FIFO#0.
