Move the dmtimer driver out of plat-omap to clocksource.
So that non-omap devices also could use this.

No Code changes done to the driver file.

 rename {arch/arm/plat-omap => drivers/clocksource}/dmtimer.c (100%)

Take the opportunity to rename it timer-dm.c

seems the drivers/clocksource subdirectory contains what its name state.
However OMAP dual mode timers have also event capture capability, which
I'd like to use to measure pulse/space width and pass measured values
to IR protocol decoders.

Do you have any idea how to split code, so that event capture capability
could be used by other drivers?

Thank you,

So in the clocksource directory the rule is the following:

The config option is silent except if COMPILE_TEST is set.

It is the Kconfig's platform which select the driver so there is no deps
on the ARCH.

config OMAP_DM_TIMER
	bool "Use dual-mode timer" if COMPILE_TEST
	help
	 Select this option if you want to use Dual-Mode timers.

Here you will have to make sure the driver compiles on x86.
