Would you want to represent everything, bit clocks, frame clocks, > master clocks etc as clock nodes? We're probably OK just going down to the master clocks mostly I think. For the clocks on the actual bus we can probably have helpers in the core that generate the clocks and the drivers just tell the core the rates. > If that's the case, could you depict how the DT bindings should look like by > example? I've not been able to dig far enough into the clock bindings yet. That's not super helpful for you I appreciate, TBH nobody seemed to particularly need this so it wasn't super urgent - most of the things using alternative clocks on devices seem to also need custom machine drivers for other reasons.
