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 ...
2013-10-16ARM: dts: Work around lack of cpufreq regulator lookup for exynos4210-origen ↵Tomasz Figa
and trats boards Exynos cpufreq drivers does not support device tree based regulator lookup, so it can get the VDD ARM regulator only by its name. To get cpufreq working for now, this patch works this around by renaming the regulator in board dts files to vdd_arm, which is the name expected by the driver. This fixes a regression introduced by dropping support of board file based bootup of Exynos 4210 boards that rendered cpufreq inoperable on Trats and Origen boards.

2012-09-21ARM: dts: Assume status of all optional nodes as disabled for exynos4Tomasz Figa
Currently all boards must explicitly disable all unused device tree nodes of unused components (e.g. i2c, sdhci, etc...). This makes it necessary to all boards to be aware of all components on the SoC, which in turns makes board dts files longer and more difficult to maintain (e.g. adding new components to SoC-level tree requires adding nodes with status="disabled" to every board). This patch changes "status" of all optional components in SoC-level dts file to "disabled", adds status="okay" to respective nodes of used components in dts of all boards and removes all nodes with only status="disabled" from boards dts.
