If I may ask - why have you dropped it?
The v5 of CCF has been posted ~2 weeks ago (with you on CC) with a high
chance to be pulled by Stefano after the merge window opens.
When we accept the "legacy" clock approach we will stuck with it for a
long time.
What approach is took by the Linux kernel? CCF or any other one?

I'm a bit skeptical about such statements. It never works like that -
after it is accepted it would become a "legacy code which we do need
to preserve".

Was the CCF the reason for the i.MX8 not being pulled for so long?
