Merge tag 'cris-for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jesper/cris
Pull arch/cris updates from Jesper Nilsson:
"Some much needed love for the CRIS-port.
There's a bunch of changes this time, giving the CRISv32 port a bit of
modern makeover with device-tree, irq domain and gpiolib support, and
more switchover to generic frameworks.
Some small fixes and removal of the theoretical SMP support brings up
the rear"
