yeah, but then one should align "frame-master" to "bitclock-master" and
several other properties.

I don't think there is benefit to order few single entries, while entire
file does not follow that convention. It would be different for some
multiple-line entries, but that's not the case here.

Anyway that's only my opinion, so I am happy to trim the patch to the
last part (although then it is a bit churn :) ).
