It would be nice to have a comment here what this will be needed for.

I see that later ipu-csi uses this to find the correct input mux and
mx6-encode selects the DMA channel depending on this.
I feel like the mux should be handled as a separate v4l2_subdev since it
is not part of the IPU, it is different between i.MX6Q and i.MX6DL, and
it doesn't even exist on i.MX5.

Philipp
