Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC DT updates from Olof Johansson: "Most of this branch consists of updates, additions and general churn of the device tree source files in the kernel (arch/arm/boot/dts). Besides that, there are a few things to point out: - Lots of platform conversion on OMAP2+, with removal of old board files for various platforms. - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well - Some updates to pinctrl and other subsystems. Most of these are for DT-enablement of the various platforms and acks have been collected" * tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (385 commits) ARM: dts: bcm11351: Use GIC/IRQ defines for sdio interrupts ARM: dts: bcm: Add missing UARTs for bcm11351 (bcm281xx) ARM: dts: bcm281xx: Add card detect GPIO ARM: dts: rename ARCH_BCM to ARCH_BCM_MOBILE (dt) ARM: bcm281xx: Add device node for the GPIO controller ARM: mvebu: Add Netgear ReadyNAS 104 board ARM: tegra: fix Tegra114 IOMMU register address ARM: kirkwood: add support for OpenBlocks A7 platform ARM: dts: omap4-panda: add DPI pinmuxing ARM: dts: AM33xx: Add RNG node ARM: dts: AM33XX: Add hwspinlock node ARM: dts: OMAP5: Add hwspinlock node ARM: dts: OMAP4: Add hwspinlock node ARM: dts: use 'status' property for PCIe nodes ARM: dts: sirf: add missed address-cells and size-cells for prima2 I2C ARM: dts: sirf: add missed cell, cs and dma channel for SPI nodes ARM: dts: sirf: add missed graphics2d iobg in atlas6 dts ARM: dts: sirf: add missed chhifbg node in prima2 and atlas6 dts ARM: dts: sirf: add missed memcontrol-monitor node in prima2 and atlas6 dts ARM: mvebu: Add the core-divider clock to Armada 370/XP ...
