Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc device tree description updates from Arnd Bergmann: "This branch contains two kinds of updates: Some platforms in the process of getting converted to device tree based booting, and the platform specific patches necessary for that are included here. Other platforms are already converted, so we just need to update the actual device tree source files and the binding documents to add support for new board and new drivers. In the future we will probably separate those into two branches, and in the long run, the plan is to move the device tree source files out of the kernel repository, but that has to wait until we have completed a much larger portion of the binding documents." Fix up trivial conflicts in arch/arm/mach-imx/clk-imx6q.c due to newly added clkdev registers next to a few removed unnecessary ones. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (119 commits) ARM: LPC32xx: Add PWM to base dts file ARM: EXYNOS: mark the DMA channel binding for SPI as preliminary ARM: dts: Add nodes for spi controllers for SAMSUNG EXYNOS5 platforms ARM: EXYNOS: Enable platform support for SPI controllers for EXYNOS5 ARM: EXYNOS: Add spi clock support for EXYNOS5 ARM: dts: Add nodes for spi controllers for SAMSUNG EXYNOS4 platforms ARM: EXYNOS: Enable platform support for SPI controllers for EXYNOX4 ARM: EXYNOS: Fix the incorrect hierarchy of spi controller bus clock ARM: ux500: Remove PMU platform registration when booting with DT ARM: ux500: Remove temporary snowball_of_platform_devs enablement structure ARM: ux500: Ensure vendor specific properties have the vendor's identifier pinctrl: pinctrl-nomadik: Append sleepmode property with vendor specific prefixes ARM: ux500: Move rtc-pl031 registration to Device Tree when enabled ARM: ux500: Enable the AB8500 RTC for all DT:ed DB8500 based devices ARM: ux500: Correctly reference IRQs supplied by the AB8500 from Device Tree ARM: ux500: Apply ab8500-debug node do the db8500 DT structure ARM: ux500: Add a ab8500-usb Device Tree node for db8500 based devices ARM: ux500: Add db8500 Device Tree node for misc/ab8500-pwm ARM: ux500: Add db8500 Device Tree node for ab8500-sysctrl ARM: ux500: Enable LED heartbeat functionality on Snowbal via DT ...
