Hi Tero,
Have you seen Sylwester's approach[1]? 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
That assumes driver writers are aware of the clock tree topology. IME that's seldomly the case.
It assumes no such thing.
The point of Sylwester's patch is that if a driver consumes a clock and needs to do the very typical setup regarding that clock's rate or parent, then we now have a sensible way to express that in DT.
One of the strengths of DT is that the C code does not have to know all of the details about topology or how things are hooked up. We can hide some of those cute embedded nonsense hacks in DTS and the device integrator can manage it there.
Regards,
Mike
