[PATCH V3 0/5] ARM: OMAP2+: Add device-tree support for timers

[Jon Hunter]

This series adds device-tree support for the timers on OMAP2+ devices
including AM33xx.

Testing:
1. I have booted tested this series on OMAP2420 H4, OMAP3430 Beagle, OMAP4430
   Panda and AM335x Beagle Bone with/without ...
   a). device-tree present
   b). CONFIG_OMAP_32K_TIMER set
   c). kernel boot parameter "clocksource=gp_timer" present
2. I have tested the all the timers (not used by the kernel as sys-timers) on
   OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda with/without device-tree with
   this series. The testing includes ...
   a. Configuring, starting a timer and checking the counter value is
      incrementing.
   b. Testing timer overflow interrupt when timer expires.
   c. Using different clock sources to operate the timer with.

V3 changes:
- Removed definition "TIMER_PROP_ALWON" per Rob Herring's feedback
- Updated OMAP system timer (clock-events and clock-source) code so that
  HWMOD is NOT used for getting resource (memory and interrupt) information
  when device-tree is present.

V2 changes:
- Remove use of device-tree alias property
- Migrate OMAP timers to request timers by property instead of device ID
- Include OMAP2 support
