[PATCH V2 3/4] dt-bindings: media: ti: vpe: Add bindings for Video Input Port

From: Dale Farnsworth <dale at farnsworth.org>

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.

Changelog:
Changes in v2:
- Remove array and just use hsync: true in bindings
- Remove array and use enum for bus width in bindings
- Use pattern properties since properties across ports are same
- Update copyright year

+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 at 0 -> Slice 0 Port A
+    port at 1 -> Slice 0 Port B
+    port at 2 -> Slice 1 Port A
+    port at 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.yaml.
