[RFC PATCH 7/8] arm64: dts: ti: k3-am62a7: FPDLink overlays for LI OV2312
From: Rishikesh Donadkar
Date: Fri Sep 25 2026 - 09:34:29 EST
From: Jai Luthra <j-luthra@xxxxxx>
OV2312 is a raw (4x4 RGB-IR bayer) sensor, the LI-OV2312-FPDLinkIII-110H
module [1] packages it with an FPDLink-III serializer (DS90UB953) for
use with sensor fusion setups using FPDLink-III deserializer boards.
