[PATCH V3 1/4] media: dt-bindings: ti,ds90ub960: Refactor port definitions

From: Yemike Abhilash Chandra

Date: Fri Dec 19 2025 - 07:30:13 EST


The current bindings duplicate the port definitions for each FPD-Link RX
and CSI-2 TX ports. This results in a large amount of repeated schema
blocks and makes it harder to extend the bindings for new devices.

Refactor the bindings by introducing shared deftinitions for FPD-Link
input ports and CSI-2 output ports. No functional change intended.

Changelog:
Changes in v3:
- Remove the | character from the ports description since preserving formatting is not required. (Rob)
- Wrap the ports description at 80 characters. (Rob)
