Merge tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull arm-soc timer updates from Arnd Bergmann:
 "This contains two branches dealing with timers, one for the picoxcell
  platform that is now using DT with the platform-independent
  dw_apb_timer driver.  The other change is for the omap-specific
  dmtimer driver."

* tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  clocksource: dw_apb_timer: Add common DTS glue for dw_apb_timer
  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
