[PATCH v2 0/4] ARM: Exynos4: Add irq domain and device tree support for wakeup interrupts

[Thomas Abraham]

Changes since v1: (only patch 4/4 has changes)
- Fixes based on Rob's comments:
  a. Fixed the function prototype of exynos4_init_irq_eint(void)
  b. Included interrupt-parent as an optional property for wakeup interrupt
      controller node.

Samsung Exynos4 includes 32 external wakeup interrupt sources. This patchset
adds irq domain and device tree support for these interrupts.

This patchset is based on the following tree.
http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git  for-next

This patchset should be applied after applying the following patch.
