1* Analog Devices ADV748X video decoder with HDMI receiver
2
3The ADV7481 and ADV7482 are multi format video decoders with an integrated
4HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
5from three input sources HDMI, analog and TTL.
6
7Required Properties:
8
9  - compatible: Must contain one of the following
10    - "adi,adv7481" for the ADV7481
11    - "adi,adv7482" for the ADV7482
12
13  - reg: I2C slave addresses
14    The ADV748x has up to twelve 256-byte maps that can be accessed via the
15    main I2C ports. Each map has it own I2C address and acts as a standard
16    slave device on the I2C bus. The main address is mandatory, others are
17    optional and remain at default values if not specified.
18
19Optional Properties:
20
21  - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
22		     "intrq3". All interrupts are optional. The "intrq3" interrupt
23		     is only available on the adv7481
24  - interrupts: Specify the interrupt lines for the ADV748x
25  - reg-names : Names of maps with programmable addresses.
26		It shall contain all maps needing a non-default address.
27		Possible map names are:
28		  "main", "dpll", "cp", "hdmi", "edid", "repeater",
29		  "infoframe", "cbus", "cec", "sdp", "txa", "txb"
30
31The device node must contain one 'port' child node per device input and output
32port, in accordance with the video interface bindings defined in
33Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
34are numbered as follows.
35
36	  Name		Type		Port
37	---------------------------------------
38	  AIN0		sink		0
39	  AIN1		sink		1
40	  AIN2		sink		2
41	  AIN3		sink		3
42	  AIN4		sink		4
43	  AIN5		sink		5
44	  AIN6		sink		6
45	  AIN7		sink		7
46	  HDMI		sink		8
47	  TTL		sink		9
48	  TXA		source		10
49	  TXB		source		11
50
51The digital output port nodes, when present, shall contain at least one
52endpoint. Each of those endpoints shall contain the data-lanes property as
53described in video-interfaces.txt.
54
55Required source endpoint properties:
56  - data-lanes: an array of physical data lane indexes
57    The accepted value(s) for this property depends on which of the two
58    sources are described. For TXA 1, 2 or 4 data lanes can be described
59    while for TXB only 1 data lane is valid. See video-interfaces.txt
60    for detailed description.
61
62Ports are optional if they are not connected to anything at the hardware level.
