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

Pull m68k/colfire fixes from Greg Ungerer:
 "Only a couple of patches this time.  One migrating the clock driver
  code to the new set-state interface.  The other cleaning up to use the
  PFN_DOWN macro"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
  m68k/coldfire: use PFN_DOWN macro
  m68k/coldfire/pit: Migrate to new 'set-state' interface
