From Tony Lindgren <tony@atomide.com>:

Here are some omap dmtimer changes to make it easier to add
device tree support for dmtimer by simplifying the platform
data structure used by dmtimr.

* tag 'omap-devel-dmtimer-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Simplify dmtimer clock aliases
  ARM: OMAP2+: Move dmtimer clock set function to dmtimer driver
  ARM: OMAP1: Fix dmtimer support
  ARM: OMAP: Add flag to indicate if a timer needs a manual reset
  ARM: OMAP: Remove timer function pointer for context loss counter
  ARM: OMAP: Remove loses_context variable from timer platform data
  ARM: OMAP2+: Fix external clock support for dmtimers
  ARM: OMAP2+: HWMOD: Correct timer device attributes
  ARM: OMAP: Add DMTIMER capability variable to represent timer features
  ARM: OMAP2+: Add dmtimer platform function to reserve systimers
  ARM: OMAP2+: Remove unused max number of timers definition
  ARM: OMAP: Remove unnecessary clk structure
