This reverts commit 82c2ffeb21 ("[media] tvp5150: document input
connectors DT bindings") since the DT binding is too device driver
specific and should instead be more generic and use the bindings
in Documentation/devicetree/bindings/display/connector/ and linked
to the tvp5150 using the OF graph port and endpoints.
There are still ongoing discussions about how the input connectors
will be supported by the Media Controller framework so until that
is settled, it is better to revert the connectors portion of the
bindings to avoid known to be broken bindings docs to hit mainline.

* Texas Instruments TVP5150 and TVP5151 video decoders
|
|
|
|
The TVP5150 and TVP5151 are video decoders that convert baseband NTSC and PAL
|
|
(and also SECAM in the TVP5151 case) video signals to either 8-bit 4:2:2 YUV
|
|
with discrete syncs or 8-bit ITU-R BT.656 with embedded syncs output formats.
|
|
|
|
Required Properties:
|
|
- compatible: value must be "ti,tvp5150"
|
|
- reg: I2C slave address
|
|
|
|
Optional Properties:
|
|
- pdn-gpios: phandle for the GPIO connected to the PDN pin, if any.
|
|
- reset-gpios: phandle for the GPIO connected to the RESETB pin, if any.
|
|
|
|
The device node must contain one 'port' child node for its digital output
|
|
video port, in accordance with the video interface bindings defined in
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt.
|
|
|
|
Required Endpoint Properties for parallel synchronization:
|
|
|
|
- hsync-active: active state of the HSYNC signal. Must be <1> (HIGH).
|
|
- vsync-active: active state of the VSYNC signal. Must be <1> (HIGH).
|
|
- field-even-active: field signal level during the even field data
|
|
transmission. Must be <0>.
|
|
|
|
If none of hsync-active, vsync-active and field-even-active is specified,
|
|
the endpoint is assumed to use embedded BT.656 synchronization.
|
|
|
|
Example:
|
|
|
|
&i2c2 {
|
|
...
|
|
tvp5150@5c {
|
|
compatible = "ti,tvp5150";
|
|
reg = <0x5c>;
|
|
pdn-gpios = <&gpio4 30 GPIO_ACTIVE_LOW>;
|
|
reset-gpios = <&gpio6 7 GPIO_ACTIVE_LOW>;
|
|
|
|
port {
|
|
tvp5150_1: endpoint {
|
|
remote-endpoint = <&ccdc_ep>;
|
|
};
|
|
};
|
|
};
|
|
};
