Thanks for all your work, I was about to apply it but as I already
applied your previous patches I didn't manage to do it.

Would you mind rebasing your patch on the mvebu/dt branch that I have
just push on git://git.infradead.org/linux-mvebu.git ?

If not, I think I would manage to do it for you.

Thanks again,

Gregory
