I wonder if there is anything preventing us from putting it all into linux-4.16.
This is low-risk (nothing would break), and the other three arch/arm64 patches
are trivial, so if someone can do a review quickly, I'd be willing to pick the
arm-soc portion up.

I suppose we need the clk and pintrl drivers to also get merged at the
same time to make it usable, and we also want the bindings for pinctrl
and clk to be properly reviewed before adding the nodes to the DT
so it depends a, bit on the other maintainers.

To me it looks like the drivers are just "yet another i.MX variant" for them,
it should make little difference that this one is 64-bit.
