This patch series implements dmtimer hwmod.
Maybe the description should be a little bit more detailed:
Something like "Adapt dmtimer code to platform_driver using omap_device
/ omap_hwmod abstraction"

Version 3
*********
(1) multi-line comment error correction
(2) provision to allow any of the available dmtimers as early timers
instead of restricting them to millisecond timers only.
(3) in 'struct omap_dmtimer{}' is_initialized flag is redundant and
so must be removed. if the element is found in the list it is already
initialized.
(4) remove 'found' flag in omap_dm_timer_request() and
omap_dm_timer_request_specific() functions.
this is not needed with alternate implementation.
(5) use .init_name to initialize device names so that it can be identified
during early boot as well. This is to avoid duplicate functions for clock
manipulations during early boot and later.
(6) remove redundant functions from mach-omap2 which are created just to
call pm functions like: pm_runtime_get_sync(),pm_runtime_put_sync(),..
and instead call them directly from plat-omap function api's.
(7) timer clock source names made part of hwmod database. source_clock[]
of type 'struct clk' is made part of platform data.
(8) clockactivity field initialized in hwmod database to preserve fclk
during idle. code which manipulate OCP config removed since they are
already taken care by hwmod framework.
(9) omap2_dm_timer_set_src() is optimized. Clock enable/disbale routines
moved to plat-omap layer and simplfied to the level so as not to sacrifice
intended functionality.
NOTE: During early boot clock management was requested to be placed upon
client drivers responsibility. this has not been done keeping in mind
that it would entail (i) multiple modifications of client drivers (ii) it
would violate the purpose of having a framework (open to debate).
(10) dmtimer register maps moved to hwmod database
