Merge tag 'armsoc-soc' into test-merge
ARM: SoC: platform support for v4.2
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
Conflicts:
arch/arm/mach-socfpga/core.h
Trivial remove/remove conflict with our cleanup branch.
Resolution: remove both sides
