dt-bindings: media: ti: vpe: Add support for Video Input Port
Add device tree bindings for the Video Input Port. Video Input Port (VIP)
can be found on devices such as DRA7xx and provides a parallel interface
to a video source such as a sensor or TV decoder.

Video Input Port (VIP) can be found on devices such as DRA7xx and
15

provides the system interface and the processing capability to
16

connect parallel image-sensor as well as BT.656/1120 capable encoder
17

chip to DRA7x device.

+
Each VIP instance supports 2 independently configurable external
20
+
video input capture slices (Slice 0 and Slice 1) each providing
21
+
up to two video input ports (Port A and Port B).
