Merge tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull late ARM soc platform updates from Olof Johansson: "This branch contains updates to OMAP and Marvell platforms (kirkwood, dove, mvebu) that came in after we had done the big multiplatform merges, so they were kept separate from the rest, and not separated into the traditional topics of cleanup/driver/platform features. For OMAP, the updates are: - Runtime PM conversions for the GPMC and RNG IP blocks - Preparation patches for the OMAP common clock framework conversion - clkdev alias additions required by other drivers - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4 - OMAP hwmod code and data improvements - Preparation patches for the IOMMU runtime PM conversion - Preparation patches for OMAP4 full-chip retention support For Kirkwood/Dove/mvebu: - New driver for "address decoder controller" for mvebu, which is a piece of hardware that configures addressable devices and peripherals. First user is the boot rom aperture on armada XP since it is needed for SMP support. - New device tree bindings for peripherals such as gpio-fan, iconnect nand, mv_cesa and the above address decoder controller. - Some defconfig updates, mostly to enable new DT boards and a few drivers. - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu - New clean gpio driver for mvebu" * tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (98 commits) ARM: mvebu: fix build breaks from multi-platform conversion ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70 ARM: OMAP2+: PMU: Add runtime PM support ARM: OMAP4430: PMU: prepare to create PMU device via HWMOD ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMOD ARM: OMAP3: hwmod data: Add debugss HWMOD data ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problems ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP hwrng: OMAP: remove SoC restrictions from driver registration ARM: OMAP: split OMAP1, OMAP2+ RNG device registration hwrng: OMAP: convert to use runtime PM hwrng: OMAP: store per-device data in per-device variables, not file statics ARM: OMAP2xxx: hwmod/CM: add RNG integration data ARM: OMAP2+: gpmc: minimal driver support ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2/3: hwmod data: add gpmc ARM: OMAP4: hwmod data: add mmu hwmod for ipu and dsp ARM: OMAP3: hwmod data: add mmu data for iva and isp ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selected ARM: OMAP4: hwmod data: add missing HWMOD_NO_IDLEST flags to some PRCM IP blocks ...
