Subject: [PATCH V4 3/4] dt-bindings: media: ti: vpe: Add support for Video Input Port
From: Dale Farnsworth <dale@...nsworth.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 v4:
Krzysztof:
- Fix title
- Drop configuration parameters
- Remove redundant remote-endpoint
- Have one contiguous address space as defined by TRM.
- Make example complete by adding endpoints to all VIP instances
