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 address
18 - hpd-gpios: References to the GPIOs that control the HDMI hot-plug
19 detection pins, one per HDMI input. The active flag indicates the GPIO
20 level that enables hot-plug detection.
22 The device node must contain one 'port' child node per device input and output
23 port, in accordance with the video interface bindings defined in
24 Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
25 are numbered as follows.
28 ------------------------------------------------------------
32 The digital output port node must contain at least one endpoint.
36 - reset-gpios: Reference to the GPIO connected to the device's reset pin.
37 - default-input: Select which input is selected after reset.
39 Optional Endpoint Properties:
41 The following three properties are defined in video-interfaces.txt and are
42 valid for source endpoints only.
44 - hsync-active: Horizontal synchronization polarity. Defaults to active low.
45 - vsync-active: Vertical synchronization polarity. Defaults to active low.
46 - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
48 If none of hsync-active, vsync-active and pclk-sample is specified the
49 endpoint will use embedded BT.656 synchronization.
