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

Pull "ARM: timer cleanup work" from Arnd Bergmann:
 "These are split out from the generic soc and driver updates because
  there was a lot of conflicting work by multiple people.  Marc Zyngier
  worked on simplifying the "localtimer" interfaces, and some of the
  platforms are touching the same code as they move to device tree based
  booting.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"
