Hi,
I'm trying to get a camera stream on our i.MX8MM board up and running
with Linux 6.1. I'm using the RPi v2.1 camera module (imx219) as sensor.
I basically copied the devicetree setup from Tim's overlay at
arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-imx219.dts.
With all the drivers enabled the devices (imx219, imx7-media-csi,
imx-mipi-csis) seem to probe just fine and I see /dev/video0 and
/dev/media0.
For the v4l subdevices I would expect to see one for the sensor and one
for the CSI bridge. But only the latter is there (see below).
Is this correct? Am I missing something? How can I setup/enable the
pipeline/stream?
Thanks for any help!
