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.
11 - iovcc-supply: I/O Supply Voltage (1.8V or 3.3V)
12 - cvcc12-supply: Digital Core Supply Voltage (1.2V)
14 HDMI audio properties:
15 - #sound-dai-cells: <0> or <1>. <0> if only i2s or spdif pin
16 is wired, <1> if the both are wired. HDMI audio is
17 configured only if this property is found.
18 - sil,i2s-data-lanes: Array of up to 4 integers with values of 0-3
19 Each integer indicates which i2s pin is connected to which
20 audio fifo. The first integer selects i2s audio pin for the
21 first audio fifo#0 (HDMI channels 1&2), second for fifo#1
22 (HDMI channels 3&4), and so on. There is 4 fifos and 4 i2s
23 pins (SD0 - SD3). Any i2s pin can be connected to any fifo,
24 but there can be no gaps. E.g. an i2s pin must be mapped to
25 fifo#0 and fifo#1 before mapping a channel to fifo#2. Default
26 value is <0>, describing SD0 pin beiging routed to hdmi audio
28 - clocks: phandle and clock specifier for each clock listed in
29 the clock-names property
31 Describes SII902x MCLK input. MCLK can be used to produce
32 HDMI audio CTS values. This property follows
33 Documentation/devicetree/bindings/clock/clock-bindings.txt
36 If HDMI audio is configured the sii902x device becomes an I2S
37 and/or spdif audio codec component (e.g a digital audio sink),
38 that can be used in configuring a full audio devices with
39 simple-card or audio-graph-card binding. See their binding
40 documents on how to describe the way the sii902x device is
41 connected to the rest of the audio system:
42 Documentation/devicetree/bindings/sound/simple-card.yaml
43 Documentation/devicetree/bindings/sound/audio-graph-card.txt
44 Note: In case of the audio-graph-card binding the used port
48 - video input: this subnode can contain a video input port node
49 to connect the bridge to a display controller output (See this
