That's not going as fast as I hoped. This driver is quite complex and extracting
it from soc-camera isn't easy. I also can't spend as much time as I'd like on this.

At best this will be a temporary helper source. I never liked soc_mediabus, I don't
believe it is the right approach. But I have no problem if it is used for now to
simplify the soc-camera dependency removal.

Can you provide the output of 'v4l2-compliance -s' with your new pxa driver?
I would be curious to see the result of that.
