* 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 per device physical input
and output port, in accordance with the video interface bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
are numbered as follows
Name Type Port
--------------------------------------
AIP1A sink 0
AIP1B sink 1
Y-OUT src 2
The device node must contain at least one sink port and the src port. Each input
port must be linked to an endpoint defined in
Documentation/devicetree/bindings/display/connector/analog-tv-connector.txt. The
port/connector layout is as follows
tvp-5150 port@0 (AIP1A)
endpoint@0 -----------> Comp0-Con port
endpoint@1 ------+----> Svideo-Con port
tvp-5150 port@1 (AIP1B) |
endpoint@1 ------+
endpoint@0 -----------> Comp1-Con port
tvp-5150 port@2
endpoint (video bitstream output at YOUT[0-7] parallel bus)
Required Endpoint Properties for parallel synchronization on output port:
- 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 - three input sources:
comp_connector_0 {
compatible = "composite-video-connector";
label = "Composite0";
port {
composite0_to_tvp5150: endpoint {
remote-endpoint = <&tvp5150_to_composite0>;
};
};
};
comp_connector_1 {
compatible = "composite-video-connector";
label = "Composite1";
port {
composite1_to_tvp5150: endpoint {
remote-endpoint = <&tvp5150_to_composite1>;
};
};
};
svideo_connector {
compatible = "svideo-connector";
label = "S-Video";
port {
#address-cells = <1>;
#size-cells = <0>;
svideo_luma_to_tvp5150: endpoint@0 {
reg = <0>;
remote-endpoint = <&tvp5150_to_svideo_luma>;
};
svideo_chroma_to_tvp5150: endpoint@1 {
reg = <1>;
remote-endpoint = <&tvp5150_to_svideo_chroma>;
};
};
};
&i2c2 {
tvp5150@5c {
compatible = "ti,tvp5150";
reg = <0x5c>;
pdn-gpios = <&gpio4 30 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpio6 7 GPIO_ACTIVE_LOW>;
#address-cells = <1>;
#size-cells = <0>;
port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
tvp5150_to_composite0: endpoint@0 {
reg = <0>;
remote-endpoint = <&composite0_to_tvp5150>;
};
tvp5150_to_svideo_luma: endpoint@1 {
reg = <1>;
remote-endpoint = <&svideo_luma_to_tvp5150>;
};
};
port@1 {
#address-cells = <1>;
#size-cells = <0>;
reg = <1>;
tvp5150_to_composite1: endpoint@0 {
reg = <0>;
remote-endpoint = <&composite1_to_tvp5150>;
};
tvp5150_to_svideo_chroma: endpoint@1 {
reg = <1>;
remote-endpoint = <&svideo_chroma_to_tvp5150>;
};
};
port@2 {
reg = <2>;
tvp5150_1: endpoint {
remote-endpoint = <&ccdc_ep>;
};
};
};
};
