Thanks for your feedback!

Sure, that is fine with me. I based the ones above on already existing ones used by SH but I don't mind reworking those.
How about SYS_SUPPORTS_CLKSRC_xxx?

I have any strong feelings one way or the other about that myself, but I got the impression that John Stultz preferred to not allow manual selection at all, and my compromise here is to allow it only when COMPILE_TEST is selected.
Would you be ok to keep it as-is for now? If needed then we can add an incremental patch later to enable more flexible selection.
Thanks,
