could you please change your patch to describe why you need to add this pinmux?

I'm working on a board that is wired that way. I can of course put this
in the board-specific dts if that's preferable.

So the board isn't submitted to mainline?
IMHO the change is okay, but the description doesn't explain why is it needed.
So a suitable description would be that it's needed for board xy.

Not yet anyway.

Would it be better to send this patch in a series along with the full
board support?

Yes, it would be nice to have a dts file which reference the new pinmux.

OK, I'll sit on it for a while longer then.

The problem with pinmuxing on i.MX23/28 is that the order of pinmux
groups is to a certain degree important. So not everything is possible
in the machine specific dts. (I didn't have an eye on this issue, maybe
it's fixed in the meantime?)
Best regards
Uwe
