OK cool, but I just realized that this driver was added just two
years ago by Gabor and Miguel, so I'd like to get their feedback
before continuing.

I know I already merged the DT support and stuff, but better
late than never.

Please include them on future postings of patches to this
driver... (See To: line)

Miguel, Gabor: please look at this, I hope you can get hold
of the patches. Please also check the stuff I've already merged
here:
