That's a pipedream.  It really is.  Some of those are impossible to
convert because you don't have enough timers/counters to provide the
clocksource and clockevents - as I've mentioned several times in the
past.

clocksource and clockevents are all very nice and such, but they don't
always fit real hardware.
