1 * Analog Devices ADV7604/11/12 video decoder with HDMI receiver
3 The ADV7604 and ADV7611/12 are multiformat video decoders with an integrated
4 HDMI receiver. The ADV7604 has four multiplexed HDMI inputs and one analog
5 input, and the ADV7611 has one HDMI input and no analog input. The 7612 is
6 similar to the 7611 but has 2 HDMI inputs.
8 These device tree bindings support the ADV7611/12 only at the moment.
12 - compatible: Must contain one of the following
13 - "adi,adv7611" for the ADV7611
14 - "adi,adv7612" for the ADV7612
16 - reg: I2C slave addresses
17 The ADV76xx has up to thirteen 256-byte maps that can be accessed via the
18 main I2C ports. Each map has it own I2C address and acts as a standard
19 slave device on the I2C bus. The main address is mandatory, others are
20 optional and revert to defaults if not specified.
22 - hpd-gpios: References to the GPIOs that control the HDMI hot-plug
23 detection pins, one per HDMI input. The active flag indicates the GPIO
24 level that enables hot-plug detection.
26 The device node must contain one 'port' child node per device input and output
27 port, in accordance with the video interface bindings defined in
28 Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
29 are numbered as follows.
32 ------------------------------------------------------------
36 The digital output port node must contain at least one endpoint.
40 - reset-gpios: Reference to the GPIO connected to the device's reset pin.
41 - default-input: Select which input is selected after reset.
42 - reg-names : Names of maps with programmable addresses.
43 It can contain any map needing a non-default address.
44 Possible maps names are :
45 "main", "avlink", "cec", "infoframe", "esdp", "dpp", "afe",
46 "rep", "edid", "hdmi", "test", "cp", "vdp"
48 Optional Endpoint Properties:
50 The following three properties are defined in video-interfaces.txt and are
51 valid for source endpoints only.
53 - hsync-active: Horizontal synchronization polarity. Defaults to active low.
54 - vsync-active: Vertical synchronization polarity. Defaults to active low.
55 - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
57 If none of hsync-active, vsync-active and pclk-sample is specified the
58 endpoint will use embedded BT.656 synchronization.
