It looks like you're missing homestar, aren't you? I'd expect that
after applying your change that:

git grep -A1 include.*sc7180-trogdor.dtsi

...should show your new include right after all includes of
sc7180-trogdor.dtsi, but I don't see it for homestar.

Other than that this looks good to me. Feel free to add my Reviewed-by.
