| * 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. |
| |
| Optional nodes: |
| - connectors: The input connectors of tvp5150 have to be defined under |
| a subnode name "connectors" using the following format: |
| |
| input-connector-name { |
| input connector properties |
| }; |
| |
| Each input connector must contain the following properties: |
| |
| - label: a name for the connector. |
| - input: the input connector. |
| |
| The possible values for the "input" property are: |
| 0: Composite0 |
| 1: Composite1 |
| 2: S-Video |
| |
| and on a tvp5150am1 and tvp5151 there is another: |
| 4: Signal generator |
| |
| The list of valid input connectors are defined in dt-bindings/media/tvp5150.h |
| header file and can be included by device tree source files. |
| |
| Each input connector can be defined only once. |
| |
| 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>; |
| |
| connectors { |
| composite0 { |
| label = "Composite0"; |
| input = <TVP5150_COMPOSITE0>; |
| }; |
| |
| composite1 { |
| label = "Composite1"; |
| input = <TVP5150_COMPOSITE1>; |
| }; |
| |
| s-video { |
| label = "S-Video"; |
| input = <TVP5150_SVIDEO>; |
| }; |
| }; |
| |
| port { |
| tvp5150_1: endpoint { |
| remote-endpoint = <&ccdc_ep>; |
| }; |
| }; |
| }; |
| }; |
