Hi Paul,
No, the sleeping clock case is and always will be a corner case, and I have no interest in pretending otherwise. On SH we have hundreds of clocks that are all usable in the atomic context and perhaps less than a dozen that aren't (and even in those cases much of the PLL negotiation is handled in hardware so there's never any visibility for the lock-down from the software side, other architectures also have similar behaviour).
I'm not too worried about the corner-cases on the *implementation* side, more the corner-cases on the API side: are we seeing more users of the API that require an atomic clock, or more that don't care? Cheers, Jeremy
