Yeah, we had it as two and converged to this one. The thing is, the rest of the attrs are the same for both parent pin and parent device. I link it this way a bit better.

Could be, but what't the benefit? Also, you are not configuring pin-parent. You are configuring pin:pin-parent tuple. Basically the pin configuration as a child. So this is mainly config of the pin itsest Therefore does not really make sense to me to split to two comments.
