[PATCH] dt-bindings: pinctrl: uniphier: add UniPhier pinctrl binding

[Masahiro Yamada]

The driver has been in the tree for a while, but its binding document
is missing.  Hence, here it is.

There's not a contiguous register range that can be put here?

Right.

I saw SATA PHY registers are inserted among the pinctrl registers.

Hardware engineers often make crazy design.

Okay,

Acked-by: Rob Herring <robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

> Hardware engineers often make crazy design.

If there's 2 ways to do things, they will find a 3rd way.
