I we'll need to continue that work as well, unfortunately I've had higher
priority things to do. Still, getting that right is complex and will take
time. The V4L2 pixel format for this sensor will likely be a
hardware-specific one for quite a while: this sensor in question sends
several frames in different formats of a single image at once which doesn't
match to V4L2's pixel format configuration that assumes a single format.

Kind regards,
