[PATCH v2 0/4] arm64: dts: ti: Enable camera for SK-AM62P

From: Jai Luthra
Date: Tue Feb 20 2024 - 01:18:31 EST


This series enables support for camera sensors using CSI-RX ports on
AM62P family of SoCs.

Particularly, it enables OV5640 and IMX219 sensors via the 22-pin FFC
CSI-RX connector on SK-AM62P [1] using the existing common overlays for
SK-AM62* family of boards.
