I mentioned because in v1 you were already exposing the channels with V4L2_SUBDEV_FL_HAS_DEVNODE,
which were exposing get/set_fmt in the csi subdevice.
I can be wrong, but if I understand correctly, or you configure all the pads through the
video node, or you expose all the subdevices and let userspace to configure them, not a mix.

Helen
