That space doesn't belong there.

I understand Robs comments as meaning "ti,reset-bits" should have been
called "reset-bits" in the first place, and you shouldn't repeat adding
the vendor prefix, as that is implied by the compatible. So this should
probably be just "reset-bits".

Otherwise this looks like it should work.
