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

Pull ARM SoC platform changes from Arnd Bergmann:
 "New and updated SoC support.  Among the things new for this release
  are:

   - at91: Added support for the new SAMA5D4 SoC, following the earlier
     SAMA5D3
   - bcm: Added support for BCM63XX family of DSL SoCs
   - hisi: Added support for HiP04 server-class SoC
   - meson: Initial support for the Amlogic Meson6 (aka 8726MX) platform
   - shmobile: added support for new r8a7794 (R-Car E2) automotive SoC

  Noteworthy changes to existing SoC support are:

   - imx: convert i.MX1 to device tree
   - omap: lots of power management work
   - omap: base support to enable moving to standard UART driver
   - shmobile: lots of progress for multiplatform support, still
     ongoing"
