While a ripple counter can not usually be interfaced with (directly) from software, it may still be a crucial component in a board layout. To prevent its input clock from being disabled by the clock core because it apparently has no consumer, one needs to be able to represent that consumer in DT.
I'm okay with this as it is describing h/w, but we already 'protected-clocks' property which should work.
