    Subject[PATCH v1 11/17] ARM: dts: imx6q-apalis: Add ov5640 mipi csi camera
    Date
    From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

    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.
