[PATCH V3 4/5] dt-bindings: media: ti: vpe: Add support for Video Input Port

From: Yemike Abhilash Chandra
Date: Tue Sep 09 2025 - 04:09:39 EST

From: Dale Farnsworth <dale@xxxxxxxxxxxxxx>

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.

Change log:
Changes in v3:
- Remove redundant labels in bindings
- Remove minItems in interrupts and mandate exactly 2 interrupts using items
- Rename phandle from ti,vip-clk-polarity to ti,ctrl-module and explain why this is required by the device
- Make the phandle verifiable instead of just descriptive
- Drop entire sensor node from example DT
- Fix ports hierarchy using appropriate references and descriptions
- Use generic node names
- Add two new properties ti,vip-pixel-mux and ti,vip-channels with appropriate types and descriptions
