1* Texas Instruments TVP5150 and TVP5151 video decoders 2 3The 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 5with discrete syncs or 8-bit ITU-R BT.656 with embedded syncs output formats. 6 7Required Properties: 8==================== 9- compatible: Value must be "ti,tvp5150". 10- reg: I2C slave address. 11 12Optional 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 17The device node must contain one 'port' child node per device physical input 18and output port, in accordance with the video interface bindings defined in 19Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes 20are numbered as follows 21 22 Name Type Port 23 -------------------------------------- 24 AIP1A sink 0 25 AIP1B sink 1 26 Y-OUT src 2 27 28The device node must contain at least one sink port and the src port. Each input 29port must be linked to an endpoint defined in [1]. The port/connector layout is 30as follows 31 32tvp-5150 port@0 (AIP1A) 33 endpoint@0 -----------> Comp0-Con port 34 endpoint@1 ------+----> Svideo-Con port 35tvp-5150 port@1 (AIP1B) | 36 endpoint@1 ------+ 37 endpoint@0 -----------> Comp1-Con port 38tvp-5150 port@2 39 endpoint (video bitstream output at YOUT[0-7] parallel bus) 40 41Required 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 49Note: Do not specify any of these properties if you want to use the embedded 50 BT.656 synchronization. 51 52Optional Connector Properties: 53============================== 54 55- sdtv-standards: Set the possible signals to which the hardware tries to lock 56 instead of using the autodetection mechnism.
