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

Pull ARM SoC fixes from Olof Johansson:

 - Fix interrupt type on ethernet switch for i.MX-based RDU2

 - GPC on i.MX exposed too large a register window which resulted in
   userspace being able to crash the machine.

 - Fixup of bad merge resolution moving GPIO DT nodes under pinctrl on
   droid4.
