The timer people have already explained well enough I think, we have some 16 timers on U8500, one we use as clocksource, one for clock events and 14 are currently unused. I plan to add them as clock events as soon as there is some practical use for them. I think there is nothing stopping you from modelling some extra clock events for the remaining timers if you absolutely want to, the kernel will just disregard them currently, which is just as good/bad as the way you're exposing the custom API in these patches.
