Subject: [PATCH 400/413] 6.7: arm64: dts: imx8mp: add
|
|
imx8mp-venice-gw74xx-imx219 overlay for rpi v2 camera
|
|
|
|
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
