It feels a little fragile to rely on the organisation of the clock tree and the naming thereof. If the IP block is ever reused on an SoC with a different clock tree layout then we have to handle things differently.What do you suggest then?I will admit that I don't have a better suggestion. Without knowing which particular constraint on the mux parent clock we care about it's difficult to suggest anything useful.
There's supposed to be facilities appearing in the generic clock code for specifying default clock tree configurations via the DT - it's quite a common requirement after all. It sounds like that should be able to do the job here. Not sure if these have gone in yet or not but there's quite a bit of demand. -------------- next part -------------- A non-text attachment was scrubbed...
