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
