Either way, I would like to see an Acked-by from the device tree
maintainers for the bindings. Given that,

Acked-by: Philipp Zabel <p.zabel-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>

to merge this driver through the mips tree, since a git merge with
    git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git drivers/reset-2
is conflict free.

Philipp
