From 8fa44cad1af27e117d60ef90606aa3e824dcf855 Mon Sep 17 00:00:00 2001 From: Vitor Soares Date: Thu, 16 Jul 2026 19:43:01 +0100 Subject: [PATCH] arm64: dts: ti: k3-am62p-verdin: Add Toradex OV5640 CSI Cameras Add device tree overlays for the Toradex OV5640 CSI Cameras on Verdin AM62P CSI_1. Two variants are supported: the current CSI Camera Set 5MP OV5640 with a 27 MHz oscillator and the legacy CSI Camera Module 5MP OV5640 with a 24 MHz oscillator.
