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

Pull arm-soc sparse IRQ conversion from Arnd Bergmann:
 "The I.MX platform is getting converted to use sparse IRQs.  We are
  doing this for all platforms over time, because this is one of the
  requirements for building a multiplatform kernel, and generally a good
  idea."

* tag 'irq' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: imx: select USE_OF
