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

Pull ARM SoC fixes from Olof Johansson:
 "A handful of fixes before final release:

  Marvell Armada:
   - One to fix a typo in the devicetree specifying memory ranges for
     the crypto engine
   - Two to deal with marking PCI and device-memory as strongly ordered
     to avoid hardware deadlocks, in particular when enabling above
     crypto driver.
   - Compile fix for PM

  Allwinner:
   - DT clock fixes to deal with u-boot-enabled framebuffer (simplefb).
   - Make R8 (C.H.I.P. SoC) inherit system compatibility from A13 to
     make clocks register proper.

  Tegra:
   - Fix SD card voltage setting on the Tegra3 Beaver dev board

  Misc:
   - Two maintainers updates for STM32 and STi platforms"
