Hmm OK thanks for checking.

How about we make the system timer functions and these header
functions private to the dmtimer.c. Then we can have the SoC specific
system timer functions be selected based on comaptible value like
drivers typically do :)

I think only the SoC specific init code should be left in
arch/arm/mach-omap[12]/timer.c.
