Re: Devicetree add-on

Hello All!

Eventually I switched to using overlays.
Of course, there are some unsolved problems, such as already occupied aliases
if they are specified in the overlay, or, for example, using
"assigned-clocks" in
overlays for already probed devices. I will give two examples from my
current projects,
criticize them if it is not difficult, maybe an idea will arise on how
to do it better.
The first link with two overlays [1], the third with three [2]:)

Thanks!
