I believe the following are necessary: > CONFIG_VIDEO_IMX219=y > CONFIG_VIDEO_IMX_MIPI_CSIS=y > CONFIG_VIDEO_IMX7_CSI=y I got this working back in February with Linux 6.2-rc8 and a few additional patches (see [1]), but I haven't tried this anymore since then. In my notes I have the following commands to test the camera: media-ctl -d /dev/media0 -l "'imx219 1-0010':0 -> 'csis-32e30000.mipi-csi':0[1]" media-ctl -d /dev/media0 -V '"imx219 1-0010":0[fmt:SRGGB8_1X8/1920x1080 field:none]' media-ctl -d /dev/media0 -V '"csis-32e30000.mipi-csi":0[fmt:SRGGB8_1X8/1920x1080 field:none]' media-ctl -d /dev/media0 -V '"csi":0[fmt:SRGGB8_1X8/1920x1080 field:none]' v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --stream-mmap I currently don't have the time to look at this any closer, but maybe this already helps you in some way.
