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" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (134 commits) ARM: zx: Add basic defconfig support for ZX296702 ARM: dts: zx: add an initial zx296702 dts and doc clk: zx: add clock support to zx296702 dt-bindings: Add #defines for ZTE ZX296702 clocks ARM: socfpga: fix build error due to secondary_startup MAINTAINERS: ARM64: EXYNOS: Extend entry for ARM64 DTS ARM: ep93xx: simone: support for SPI-based MMC/SD cards MAINTAINERS: update Shawn's email to use kernel.org one ARM: socfpga: support suspend to ram ARM: socfpga: add CPU_METHOD_OF_DECLARE for Arria 10 ARM: socfpga: use CPU_METHOD_OF_DECLARE for socfpga_cyclone5 ARM: EXYNOS: register power domain driver from core_initcall ARM: EXYNOS: use PS_HOLD based poweroff for all supported SoCs ARM: SAMSUNG: Constify platform_device_id ARM: EXYNOS: Constify irq_domain_ops ARM: EXYNOS: add coupled cpuidle support for Exynos3250 ARM: EXYNOS: add exynos_get_boot_addr() helper ARM: EXYNOS: add exynos_set_boot_addr() helper ARM: EXYNOS: make exynos_core_restart() less verbose ARM: EXYNOS: fix exynos_boot_secondary() return value on timeout ...
