I don't ask for or provide guarantees, but I think we can at least *try* to keep this compatible. This version works at the moment, and should also work with future DTs - within the limits of the current driver, so only using the RC clock. It allows to later improve the accuracy by adding better input clocks - and later DT/driver combinations can make use of this. > Delaying the clock tree description to sometime in the future will only > further complicate the probe part of the driver, and there's far too > many special cases already. I don't see how this would complicate probing beyond what Allwinner brought upon us already anyway: no LOSC crystal input in this package version, but having this pin in some other SoC sharing this die (according to some BSP) sources. We can't expect a super clean driver with those HW design choices. If we really cannot keep the DT compatible, fair enough: that's what it is (there is no guarantee!), but at least we have tried.
