We'd like to get out of the business of representing pure VM clocks
as PTP devices, see:
https://lore.kernel.org/20250815113814.5e135318@kernel.org

Your driver is already in the tree which is a bit awkward but I'd
prefer to resolve that discussion before we add any more functionality
to such clocks.
