Subject: [PATCH V3 4/5] arm64: dts: imx8mm-beacon: Enable OV5640 Camera
Date: Sun, 28 Nov 2021 06:50:10 -0600 [thread overview]
Message-ID: <20211128125011.12817-4-aford173@gmail.com> (raw)
In-Reply-To: <20211128125011.12817-1-aford173@gmail.com>
The baseboard has support for a TDNext 5640 Camera which
uses an OV5640 connected to a 2-lane CSI2 interface.
With the CSI and mipi_csi2 drivers pointing to an OV5640 camera, the media
pipeline can be configured with the following:
media-ctl --links "'ov5640 1-003c':0->'imx7-mipi-csis.0':0[1]"
The camera and various nodes in the pipeline can be configured for UYVY:
media-ctl -v -V "'ov5640 1-003c':0 [fmt:UYVY8_1X16/640x480 field:none]"
media-ctl -v -V "'csi':0 [fmt:UYVY8_1X16/640x480 field:none]"
