+title: Texas Instruments DRA7x VIDEO INPUT PORT (VIP) Device Tree Bindings
+

+
+description: |-
+ The Video Input Port (VIP) is a key component for image capture
+ applications. The capture module provides the system interface and the
+ processing capability to connect parallel image-sensor as well as
+ BT.656/1120 capable encoder chip to DRA7x device.
+
+ Each VIP instance supports 2 independently configurable external video
+ input capture slices (Slice 0 and Slice 1) each providing up to two video
+ input ports (Port A and Port B) where Port A can be configured as
+ 24/16/8-bit port and Port B is fixed as 8-bit port.
+ Here these ports a represented as follows
+ port@0 -> Slice 0 Port A
+ port@1 -> Slice 0 Port B
+ port@2 -> Slice 1 Port A
+ port@3 -> Slice 1 Port B
+
+ Each camera port nodes should contain a 'port' child node with child
+ 'endpoint' node. Please refer to the bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
