Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson: "New or improved SoC support: - add support for Atmel's SAMA5D2 SoC - add support for Freescale i.MX6UL - improved support for TI's DM814x platform - misc fixes and improvements for RockChip platforms - Marvell MVEBU suspend/resume support A few driver changes that ideally would belong in the drivers branch are also here (acked by appropriate maintainers): - power key input driver for Freescale platforms (svns) - RTC driver updates for Freescale platforms (svns/mxc) - clk fixes for TI DM814/816X + a bunch of other changes for various platforms" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (83 commits) ARM: rockchip: pm: Fix PTR_ERR() argument ARM: imx: mach-imx6ul: Fix allmodconfig build clk: ti: fix for definition movement ARM: uniphier: drop v7_invalidate_l1 call at secondary entry memory: kill off set_irq_flags usage rtc: snvs: select option REGMAP_MMIO ARM: brcmstb: select ARCH_DMA_ADDR_T_64BIT for LPAE ARM: BCM: Enable ARM erratum 798181 for BRCMSTB ARM: OMAP2+: Fix power domain operations regression caused by 81xx ARM: rockchip: enable PMU_GPIOINT_WAKEUP_EN when entering shallow suspend ARM: rockchip: set correct stabilization thresholds in suspend ARM: rockchip: rename osc_switch_to_32k variable ARM: imx6ul: add fec MAC refrence clock and phy fixup init ARM: imx6ul: add fec bits to GPR syscon definition rtc: mxc: add support of device tree dt-binding: document the binding for mxc rtc rtc: mxc: use a second rtc clock ARM: davinci: cp_intc: use IRQCHIP_SKIP_SET_WAKE instead of irq_set_wake callback soc: mediatek: Fix SCPSYS compilation ARM: at91/soc: add basic support for new sama5d2 SoC ...
