I do not think the problem is to have a revert in -stable, it's more
having in in Linus tree *first* ;-)

ATM, the priority is more on fixing the regressions the initial patch
caused *for existing boards*. There were at least three boards which got
hit by first regression during 4.1-rc and a new one on the table now
that 4.1 is out. I understand your reluctance to revert the patch that
made mvneta work for your custom board but it's unfair for others that
are hit by the regressions it causes and have to spend time
bisecting/fixing it.

Anyway, if you come w/ a fix, I can commit to test it on the boards I
have.

Cheers,
