This looks like the right approach to me.

As you noted in your other email, just resyncing am33xx.dtsi isn't as
trivial as it seems as all dts/dtsi files which include this would also
need resyncing. I focused on just resyncing the files for the
BeagleBone and its derivatives as that was more manageable. I did a
quick check of am33xx.dtsi for potential incompatibilities but
obviously missed this one, thanks for sending this patch to fix it.
