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

Pull ARM SoC platform support updates from Kevin Hilman:
 "Our SoC branch usually contains expanded support for new SoCs and
  other core platform code.  Some highlights from this round:

   - sunxi: SMP support for A23 SoC
   - socpga: big-endian support
   - pxa: conversion to common clock framework
   - bcm: SMP support for BCM63138
   - imx: support new I.MX7D SoC
   - zte: basic support for ZX296702 SoC"
