Merge tag 'cris-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jesper/cris 

Pull CRIS changes from Jesper Nilsson:
 "Mostly another batch of code removal due to move to standard
  frameworks for CRISv32, initial devicetree configuration for a couple
  of boards, and some small fixes for kgdb and time handling"

* tag 'cris-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jesper/cris:
  cris: Drop reference to get_cmos_time()
  CRIS: Drop code related to obsolete or unused kconfigs
  cris: time: Cleanup of persistent clock stuff
  cris: re-use helpers to dump data in hex format
  CRIS v32: remove old GPIO and LEDs code
  CRIS v32: remove I2C bitbanging driver
  CRIS v32: add ARTPEC-3 and P1343 device trees
  CRIS v32: dev88: add GPIO, LEDs, RTC, temp sensor
  CRIS: add dt-bindings symlink
  CRIS v32: increase NR_IRQS
  cris: arch-v10: kgdb: Add '__used' for static variable is_dyn_brkp
  cris: arch-v10: kgdb: Use BAR instead of DTP0 for register P12
  cris: kgdb: use native hex2bin
