Merge tag 'integrator-irq' of... 

Merge tag 'integrator-irq' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/soc

From Linus Walleij:

This provides the following Integrator refactorings:
- Switch the FPGA IRQ controller to use the simple IRQ domain
- Get rid of preallocated IRQ descriptors on the Integrator
- Move the FPGA IRQ driver to drivers/irqchip

* tag 'integrator-irq' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator:
  ARM: plat-versatile: move FPGA irq driver to drivers/irqchip
  ARM: integrator: get rid of preallocated irq descriptors
  ARM: plat-versatile: use simple irqdomain for FPGA IRQ
