Hi Tero, Have you seen Sylwester's approach? I prefer it since it is more device-oriented and less "centralized". The clock consumer enumerates the default parent or rate of a consumed clock. This can be made to work like your approach by having the clock driver consume these clocks and set them up with default rates or parents. What do you think?
