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:
git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra.git 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.
