AFAICS, OMAP1 timer-ti-dm compatible "omap_timer" device requires OMAP16xx
at least, while I only have OMAP15xx.  Then, my testing (successful) was
limited to a single function -- omap_dm_timer_modify_idlect_mask() -- which
is called on any OMAP1 as long as CONFIG_OMAP_DM_TIMER is set (requires
CONFIG_COMPILE_TEST).  However, I've reviewed the series and it looks good
to me.  I'm only not sure if we may expect any external users of
omap_dm_timer_get_irq(), if not than we could make it local to the driver while
being at it.

For the whole series:
