Was there something I need to do here? Best regards, Tim

Add support for the RaspberryPi Camera v2 which is an IMX219 8MP module: - https://datasheets.raspberrypi.com/camera/camera-v2-schematics.pdf - has its own on-board 24MHz osc so no clock required from baseboard - pin 11 enables 1.8V and 2.8V LDO which is connected to GW74xx MIPI_GPIO4 (IMX8MP GPIO1_IO4) so we use this as a gpio Support is added via a device-tree overlay. The IMX219 supports RAW8/RAW10 image formats. Example configuration: media-ctl -l "'imx219 3-0010':0->'csis-32e40000.csi':0[1]" media-ctl -v -V "'imx219 3-0010':0 [fmt:SRGGB8/640x480 field:none]" media-ctl -v -V "'crossbar':0 [fmt:SRGGB8/640x480 field:none]" media-ctl -v -V "'mxc_isi.0':0 [fmt:SRGGB8/640x480 field:none]" v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat=RGGB v4l2-ctl --stream-mmap --stream-to=frame.raw --stream-count=1 convert -size 640x480 -depth 8 gray:frame.raw frame.png gst-launch-1.0 v4l2src ! \ video/x-bayer,format=rggb,width=640,height=480,framerate=10/1 ! \ bayer2rgb ! fbdevsink Signed-off-by: Tim Harvey <tharvey@gateworks.com> --- arch/arm64/boot/dts/freescale/Makefile | 2 + .../imx8mp-venice-gw74xx-imx219.dtso | 80 +++++++++++++++++++ 2 files changed, 82 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx-imx219.dtso
