1* Analog Devices ADV7604/11/12 video decoder with HDMI receiver
2
3The ADV7604 and ADV7611/12 are multiformat video decoders with an integrated
4HDMI receiver. The ADV7604 has four multiplexed HDMI inputs and one analog
5input, and the ADV7611 has one HDMI input and no analog input. The 7612 is
6similar to the 7611 but has 2 HDMI inputs.
7
8These device tree bindings support the ADV7611/12 only at the moment.
9
10Required Properties:
11
12  - compatible: Must contain one of the following
13    - "adi,adv7611" for the ADV7611
14    - "adi,adv7612" for the ADV7612
15
16  - reg: I2C slave address
17
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.
21
22The device node must contain one 'port' child node per device input and output
23port, in accordance with the video interface bindings defined in
24Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
25are numbered as follows.
26
27  Port			ADV7611    ADV7612
28------------------------------------------------------------
29  HDMI			0             0, 1
30  Digital output	1                2
31
32The digital output port node must contain at least one endpoint.
33
34Optional Properties:
35
36  - reset-gpios: Reference to the GPIO connected to the device's reset pin.
37
38Optional Endpoint Properties:
39
40  The following three properties are defined in video-interfaces.txt and are
41  valid for source endpoints only.
42
43  - hsync-active: Horizontal synchronization polarity. Defaults to active low.
44  - vsync-active: Vertical synchronization polarity. Defaults to active low.
45  - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
46
47  If none of hsync-active, vsync-active and pclk-sample is specified the
48  endpoint will use embedded BT.656 synchronization.
49
50  - default-input: Select which input is selected after reset.
51
52Example:
53
54	hdmi_receiver@4c {
55		compatible = "adi,adv7611";
56		reg = <0x4c>;
57
58		reset-gpios = <&ioexp 0 GPIO_ACTIVE_LOW>;
59		hpd-gpios = <&ioexp 2 GPIO_ACTIVE_HIGH>;
60
61		#address-cells = <1>;
62		#size-cells = <0>;
63
64		default-input = <0>;
65
66		port@0 {
67			reg = <0>;
68		};
69		port@1 {
70			reg = <1>;
71			hdmi_in: endpoint {
72				remote-endpoint = <&ccdc_in>;
73			};
74		};
75	};
