Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu into next 

Pull m68knommu updates from Greg Ungerer:
 "Nothing too big, just a handfull of small changes.

  A couple of dragonball fixes, coldfire qspi cleanup and fixes, and
  some coldfire gpio cleanup, fixes and extensions"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68knommu: Implement gpio support for m54xx.
  m68knommu: Make everything thats not exported, static.
  m68knommu: setting the gpio data direction register to output doesn't dependent upon the value to output!
  m68knommu: add to_irq function so we can map gpios to external interrupts.
  m68knommu: qspi declutter.
  m68knommu: Fix the 5249/525x qspi base address.
  m68knommu: Add qspi clk for Coldfire SoCs without real clks.
  m68k: fix a compiler warning when building for DragonBall
  m68knommu: Fix mach_sched_init for EZ and VZ DragonBall chips
