From de6a859c29e6624eabac0a474562290ee49850d4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 5 Sep 2025 10:40:49 +0200 Subject: [PATCH] arm64: dts: renesas: sparrow-hawk: Add overlay for IMX462 on J1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add an overlay to connect an IMX462 camera sensor to the J1 connector. The IMX462 utilizes 4 CSI-2 D-PHY lanes. This enables the video capture pipeline behind the CSI40 Rx to be enabled to process images from the sensor.
