Multiple PLLs, at least with containers and certain classes of system you
want different containers in different timespaces, especially when doing
high precision stuff where you need your system tracking say a local
master clock for syncing musical instruments and sound events while
tracking other clocks like NTP for general system time.

Put the clock type in the new fields. It becomes
u16 clock_type;
[clock type specific data]
saves having to guess.
