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 ...

+ * This driver is a fairly straightforward GPIO driver for the

+ * Kirkwood, Discovery, Armada 370/XP). The only complexity of this
+ * driver is the different register layout that exists between the
+ * non-SMP platforms (Orion, Dove, Kirkwood, Armada 370) and the SMP
+ * platforms (MV78200 from the Discovery family and the Armada
+ * XP). Therefore, this driver handles three variants of the GPIO
+ * block:
+ * - the basic variant, called "orion-gpio", with the simplest
+ * register set. Used on Orion, Dove, Kirkwoord, Armada 370 and
+ * non-SMP Discovery systems
+ * - the mv78200 variant for MV78200 Discovery systems. This variant
+ * turns the edge mask and level mask registers into CPU0 edge
+ * mask/level mask registers, and adds CPU1 edge mask/level mask
+ * registers.
+ * - the armadaxp variant for Armada XP systems. This variant keeps
+ * the normal cause/edge mask/level mask registers when the global
+ * interrupts are used, but adds per-CPU cause/edge mask/level mask
+ * registers n a separate memory area for the per-CPU GPIO
+ * interrupts.

+ * perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
+ * both have 67 MPP pins (more GPIOs and address lines for the memory
+ * bus mainly). The only difference between the mv78260 and the
+ * mv78460 in terms of pin muxing is the addition of two functions on
+ * pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
+ * cores, mv78460 has four cores).
