Ah, I see. That part is indeed an interface, so the declaration should be
in a header file that gets included by both the clocksource and the watchdog
driver.
However, you should not put all the local declarations in the header,
and the header needs to be in a location that gets included by
drivers/clocksource/arm_smp_twd.c as well. In this case, I think
it makes more sense to name that header based on the driver that
exports the function, not based on the driver that uses it,
or you can add it to an *appropriate* existing header file, if you
can find one.
An obvious choice would be arch/arm/include/asm/smp_twd.h.
