1 sii902x HDMI bridge bindings
4 - compatible: "sil,sii9022"
5 - reg: i2c address of the bridge
8 - interrupts: describe the interrupt line used to inform the host
10 - reset-gpios: OF device-tree gpio specification for RST_N pin.
12 HDMI audio properties:
13 - #sound-dai-cells: <0> or <1>. <0> if only i2s or spdif pin
14 is wired, <1> if the both are wired. HDMI audio is
15 configured only if this property is found.
16 - sil,i2s-data-lanes: Array of up to 4 integers with values of 0-3
17 Each integer indicates which i2s pin is connected to which
18 audio fifo. The first integer selects i2s audio pin for the
19 first audio fifo#0 (HDMI channels 1&2), second for fifo#1
20 (HDMI channels 3&4), and so on. There is 4 fifos and 4 i2s
21 pins (SD0 - SD3). Any i2s pin can be connected to any fifo,
22 but there can be no gaps. E.g. an i2s pin must be mapped to
23 fifo#0 and fifo#1 before mapping a channel to fifo#2. Default
24 value is <0>, describing SD0 pin beiging routed to hdmi audio
26 - clocks: phandle and clock specifier for each clock listed in
27 the clock-names property
29 Describes SII902x MCLK input. MCLK is used to produce
30 HDMI audio CTS values. This property is required if
31 "#sound-dai-cells"-property is present. This property follows

35 If HDMI audio is configured the sii902x device becomes an I2S
36 and/or spdif audio codec component (e.g a digital audio sink),
37 that can be used in configuring a full audio devices with
38 simple-card or audio-graph-card binding. See their binding
39 documents on how to describe the way the sii902x device is
40 connected to the rest of the audio system:

42 Documentation/devicetree/bindings/sound/audio-graph-card.txt
43 Note: In case of the audio-graph-card binding the used port
47 - video input: this subnode can contain a video input port node
48 to connect the bridge to a display controller output (See this
