* 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 [1]. 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>.
|
|
|
|
Note: Do not specify any of these properties if you want to use the embedded
|
|
BT.656 synchronization.
|
|
|
|
Optional Connector Properties:
|
|
==============================
|
|
|
|
- sdtv-standards: Set the possible signals to which the hardware tries to lock
|
|
instead of using the autodetection mechnism. Please look at
|
|
[1] for more information.
|
|
|
|
[1] Documentation/devicetree/bindings/display/connector/analog-tv-connector.yaml.
