1 * Texas Instruments TVP5150 and TVP5151 video decoders
2
3 The TVP5150 and TVP5151 are video decoders that convert baseband NTSC and PAL
4 (and also SECAM in the TVP5151 case) video signals to either 8-bit 4:2:2 YUV
5 with discrete syncs or 8-bit ITU-R BT.656 with embedded syncs output formats.
6
7 Required Properties:
8 ====================
9 - compatible: Value must be "ti,tvp5150".
10 - reg: I2C slave address.
11
12 Optional Properties:
13 ====================
14 - pdn-gpios: Phandle for the GPIO connected to the PDN pin, if any.
15 - reset-gpios: Phandle for the GPIO connected to the RESETB pin, if any.
16
17 The device node must contain one 'port' child node per device physical input
18 and output port, in accordance with the video interface bindings defined in
19 Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
20 are numbered as follows
21
22 Name Type Port
23 --------------------------------------
24 AIP1A sink 0
25 AIP1B sink 1
26 Y-OUT src 2
27
28 The device node must contain at least one sink port and the src port. Each input
29 port must be linked to an endpoint defined in [1]. The port/connector layout is
30 as follows
31
32 tvp-5150 port@0 (AIP1A)
33 endpoint@0 -----------> Comp0-Con port
34 endpoint@1 ------+----> Svideo-Con port
35 tvp-5150 port@1 (AIP1B) |
36 endpoint@1 ------+
37 endpoint@0 -----------> Comp1-Con port
38 tvp-5150 port@2
39 endpoint (video bitstream output at YOUT[0-7] parallel bus)
40
41 Required Endpoint Properties for parallel synchronization on output port:
42 =========================================================================
43
44 - hsync-active: Active state of the HSYNC signal. Must be <1> (HIGH).
45 - vsync-active: Active state of the VSYNC signal. Must be <1> (HIGH).
46 - field-even-active: Field signal level during the even field data
47 transmission. Must be <0>.
48
49 Note: Do not specify any of these properties if you want to use the embedded
50 BT.656 synchronization.
51
52 Optional Connector Properties:
53 ==============================
54
55 - sdtv-standards: Set the possible signals to which the hardware tries to lock
56 instead of using the autodetection mechanism. Please look at
57 [1] for more information.

59 [1] Documentation/devicetree/bindings/display/connector/analog-tv-connector.yaml.
