There's just one issue, this driver most likely only needed on
rx51 board.. So I suggest we just mark the driver depends on
ARCH_OMAP2PLUS and let's drop this patch.

This driver is already disabled for ARCH_MULTIPLATFORM
as we need to move dmtimer.c to drivers and have some minimal
include/linux/timer-omap.h for it.

Then omap_dm_timer_get_fclk() won't work on omap1 as there's no
separate functional clock. We probably should not even export
this function eventually when things are fixed up.
