From b656eb41be70e205916a1d0a80ee412690336b9d Mon Sep 17 00:00:00 2001 From: Oleksandr Suvorov Date: Wed, 15 Jun 2022 13:50:00 +0200 Subject: [PATCH] ARM: dts: imx6q-apalis: Add ov5640 mipi csi camera The Apalis iMX6 modules allow connecting a mipi-csi video input. Add support for our OV5640 camera module but have it disabled. This allows to enable it in an overlay per the current system configuration.
