[PATCH v2 17/18] arm64: dts: ti: k3-v3link: Add overlay for IMX219+UB953 serializer

From: Yemike Abhilash Chandra

Date: Mon Jul 13 2026 - 07:39:36 EST

From: Jianzhong Xu <xuj@xxxxxx>

Arducam V3Link camera solution is shipped with an UB953 serializer
and an IMX219 sensor[1]. Add an overlay for interfacing the UB953
serilaizer and IMX219 sensor with the RX0 port on the UB960 deserializer.

This overlay can be used to interface an IMX219 sensor on any platform
that supports the V3Link fusion board.

Changelog:
Changes in v2:
- Don't replacing generic V3Link fusion board DTB targets instead append new build
targets for v3link + IMX219 (sashiko)
- Add status = "okay" property in port 0 of deserializer ports (sashiko)
- Add port-specific suffixes to avoid naming collisions (sashiko)
