Architecture specific implementations for tickless kernel

I am developing a BSP for a ARM Cortex-M3 (no MMU) based board. In order to
have tickless kernel and deferrable timers, what are the architecture
specific implementations. Is the clocksource and clockevent data structures
enough? How to hook those timers to the tickless implementation of the
kernel/timer.c. Can some one point out any examples that already have this
feature enabled and also in the kernel tree.
And also, are clocksoure and clockevents dependent on each other? I see in
some platforms, that they have used 2 different timers for the above. If it
can be used so, which ties up the clocksource and clockevent?
Thanks in advance
