    Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
    
    Pull ARM SoC fixes from Olof Johansson:
     "The first real batch of fixes for this release cycle, so there are a
      few more than usual.
    
      Most of these are fixes and tweaks to board support (DT bugfixes,
      etc).  I've also picked up a couple of small cleanups that seemed
      innocent enough that there was little reason to wait (const/
      __initconst and Kconfig deps).
    
      Quite a bit of the changes on OMAP were due to fixes to no longer
      write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but
      there were also other fixes.
    
      Kirkwood had a bunch of gpio fixes for some boards.  OMAP had RTC
      fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.
    
      All in all, mostly the usual mix of various fixes"
