Does this match the kernel? Or does the kernel have no such binding yet?

There are no such bindings in the kernel yet. Dynamic pinmuxing is not supported by the Arria 10; so we don't anticipate the kernel needing pinmux information.

OK. Currently device tree files are stored in the kernel, so it might be worth submitting it there one day regardless.

Actually, I believe you should use standard pinmux format. Just because dynamic pinmuxing is not supported now does not mean it will not be supported in Arria 11... And it was already supported in older chipsets (right?).
