struct sys_timer has been deleted; the patches to do so are in the most
recent 2 linux-next. Another advantage of this change if your SoC
supports DT is that you don't need to explicitly prototype a separate
struct or function per clocksource driver, but board files can simply
call clocksource_of_init(), and the core code will look up the
appropriate clocksource driver to initialize using DT.

You can find the series at:

arm-timer-rework

I believe that branch should be stable now unless any bugs are found so
you can base your changes on it; I plan to send a pull request to
include that branch in arm-soc tomorrow morning.
