+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
-Required Endpoint Properties for parallel synchronization:
+ Name Type Port
+ --------------------------------------
+ AIP1A sink 0
+ AIP1B sink 1
+ Y-OUT src 2
-- 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>.
+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
-If none of hsync-active, vsync-active and field-even-active is specified,
-the endpoint is assumed to use embedded BT.656 synchronization.

+- vsync-active: Active state of the VSYNC signal. Must be <1> (HIGH).
+- field-even-active: Field signal level during the even field data

+Note: Do not specify any of these properties if you want to use the embedded

+- sdtv-standards: Set the possible signals to which the hardware tries to lock
+ instead of using the autodetection mechnism. Please look at
