[RFC 0/4] ARM: OMAP3+: Add device-tree support for dmtimers

This series adds device-tree support for the dmtimers on OMAP3/4 devices. Once
everyone is happy with the implementation I can add support for OMAP2/5 devices
too.

Testing:
- I have tested the all the dmtimers (not used by the kernel as sys-timers) on
  both OMAP3430 Beagle and OMAP4460 Panda with/without device-tree with this
  series.
- The testing includes
	- Configuring, starting a timer and checking the counter value is
	  incrementing.
	- Testing timer overflow interrupt when timer expires.
	- Using different clock sources to operate the timer with.
	- Using DT to provide resource information for IRQ and memory by
	  removing Benoit's intention "HACK" in commit a4f6cdb0 (ARM: OMAP:
	  omap_device: Add omap_device_[alloc|delete] for DT integration)

Jon Hunter (4):
  arm/dts: OMAP: Add genernal purpose timer nodes
  ARM: OMAP3: Dynamically disable secure timer nodes for secure devices
  ARM: OMAP4: Add timer clock aliases for device-tree
  ARM: OMAP: Add DT support for dmtimer driver
