I would say that the latest addition to the TODO file is quite valid ;)
We have been looking at moving the mxs-lradc out of staging for a while
now. It still has a few contributions coming from time to time and can
definitely be improved. The main thing to do would be to create an MFD.

I understand this may be a considerable amount of work but it has the
advantage of allowing to have a look at at least 3 different subsystems.

I am willing to review and test patches.

I would suggest that board:
http://www.crystalfontz.com/product/CFA921TS

It may not be the cheapeast one but it has good mainline support and I
know it well.

Crystalfontz provided me some of their boards so that I could give them
out at ELC. If you are interested in the topic, it may be worth asking
whether they are willing to sponsor you ;)
