Overall very nice, just waiting for the next version.

And that binding defines that we have a register named "dat".

And then this too.

Do we want these generic MMIO bindings (dat, no-output)
in a special document like
Documentation/devicetree/bindings/gpio/gpio-mmio.txt?

Going forward?

This patch set mainly deals with refactorings, but in the
long run we want to slim things down a bit and use standard
bindings I think.
