* 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>;
|
|
};
|
|
};
|
|
};
|
|
};
