Merge tag 'at91-drivers-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux 

Pull AT91 reset, poweroff and ram drivers from Maxime Ripard:
 "This tag holds the various new drivers introduced to move code that used to be
  in mach-at91 over to the proper frameworks.

  These files are the reboot and poweroff code for all AT91 SoCs but the RM9200,
  and the ram controller driver is not doing much at the time, except for grabing
  the RAM clock in order to leave it always enabled."
