I guess this stuff is dependent on the stuff Fabio has recently sent to
Felipe for the ux500 musb DMA so these musb patches should
primarily go through his tree.

It seems like the later changes to the platform code
(arch/arm/mach-ux500) may be sufficiently orthogonal
so it can be done out-of-order?

I can't merge any of this without Felipes ACKs in any
case.

Yours,
Linus Walleij
