If you have or have already planned to write such platform, machine
or subsystem drivers, it's OK, if there are no such users and you cannot
easily give one, it's overdesigned IMHO. Some realistic examples of such
drivers will make me change my mind :-)

The reason I persist is that I've seen such unutilized timer API:s before and
no other user than the system timer in sight. I never understood what they
were to be used for, and I still don't, so help me understand. The kernel
has many internal timer API:s based on clockevent available already so
why add yet another, platform-specific one?
