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 usual batch; most of them are DT tweaks to fix misdescribed
  hardware. Beyond that:

   - A bugfix for MMP2 CPU detection, it's been there quite a while but
     makes sense to fix now anyway.

   - Some power management tweaks:
      + disabling of CPU idle power state on Marvell Armada 7K/8K
        (Macchiatobin et al)
      + Increase of minimum voltage on BananaPi M3
      + Tweak of power ramp time for DVFS on NXP/Freescale i.MX7SX

   - A couple of MAINTAINER updates:
      + MMP has a new volunteer to look after it
      + Mediatek adds a few keywords, IRC channel and wiki URL"
