I've found the framework quite convenient and comfortable, it
definitely saves a lot of work and coding once you understand it
properly.
For a simple device as i.MX2 eMMa-PrP a driver can be in a working
state in a couple of days. I've not found any drawbacks.

It depends on the result of a proof of concept we are preparing now.
But yes, it could be possible. AFAIK, Sascha Hauer (added to CC) has a
prototype driver for this one though.

It seems I'll have to prepare a second version with all the fixes
you've pointed out which seem quite reasonable to me.

Regards.
