Subject: [PATCH V2 3/3] arm64: dts: imx8mn-beacon:  Add support for OV5640 Camera
Date: Sun,  7 May 2023 10:15:48 -0500	[thread overview]
Message-ID: <20230507151549.1216019-3-aford173@gmail.com> (raw)
In-Reply-To: <20230507151549.1216019-1-aford173@gmail.com>

The baseboard has a very specific pinout for the TD Next 5640
camera which uses an OV5640 sensor.  Enable it as part of the
deveopment kit baseboard instead of an overlay.

Enable the camera with the following
  media-ctl -l "'ov5640 1-0010':0 -> 'csis-32e30000.mipi-csi':0 [1]"
  media-ctl -v -V "'ov5640 1-0010':0 [fmt:UYVY8_1X16/640x480 field:none]"
  media-ctl -v -V "'crossbar':0 [fmt:UYVY8_1X16/640x480 field:none]"
  media-ctl -v -V "'mxc_isi.0':0 [fmt:UYVY8_1X16/640x480 field:none]"
