Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC platform updates from Olof Johansson: "Most of these are for MMP (seeing a bunch of cleanups and refactorings for the first time in a while), and for OMAP (a bunch of cleanups and added support for voltage controller on OMAP4430)" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (51 commits) ARM: OMAP2+: Add missing put_device() call in omapdss_init_of() OMAP2: fixup doc comments in omap_device ARM: OMAP1: drop duplicated dependency on ARCH_OMAP1 ARM: ASPEED: update default ARCH_NR_GPIO for ARCH_ASPEED ARM: imx: use generic function to exit coherency ARM: tegra: Use WFE for power-gating on Tegra30 ARM: tegra: Fix FLOW_CTLR_HALT register clobbering by tegra_resume() ARM: exynos: Enable exynos-asv driver for ARCH_EXYNOS ARM: s3c: Rename s5p_usb_phy functions ARM: s3c: Rename s3c64xx_spi_setname() function ARM: imx: Add serial number support for i.MX6/7 SoCs ARM: imx: Drop imx_anatop_usb_chrg_detect_disable() arm64: Introduce config for S32 ARM: hisi: drop useless depend on ARCH_MULTI_V7 arm64: realtek: Select reset controller ARM: shmobile: rcar-gen2: Drop legacy DT clock support ARM: OMAP2+: Remove duplicated include from pmic-cpcap.c ARM: OMAP1: ams-delta FIQ: Fix a typo ("Initiaize") MAINTAINERS: Add logicpd-som-lv and logicpd-torpedo to OMAP TREE ARM: OMAP2+: pdata-quirks: drop TI_ST/KIM support ...
