Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree changes from Arnd Bergmann: "These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing. A number of platforms change their DT files to use the C preprocessor, which is causing a bit of churn, but that is hopefully only this once" * tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (372 commits) ARM: at91: dt: rm9200ek: add spi support ARM: at91: dt: rm9200: add spi support ARM: at91/DT: at91sam9n12: add SPI DMA client infos ARM: at91/DT: sama5d3: add SPI DMA client infos ARM: at91/DT: fix SPI compatibility string ARM: Kirkwood: Fix the internal register ranges translation ARM: dts: bcm281xx: change comment to C89 style ARM: mmc: bcm281xx SDHCI driver (dt mods) ARM: nomadik: add the new clocks to the device tree clk: nomadik: implement the Nomadik clocks properly ARM: dts: omap5-uevm: Provide USB Host PHY clock frequency ARM: dts: omap4-panda: Fix DVI EDID reads ARM: dts: omap4-panda: Add USB Host support arm: mvebu: enable mini-PCIe connectors on Armada 370 RD ARM: shmobile: irqpin: add a DT property to enable masking on parent ARM: dts: AM43x EPOS EVM support ARM: dts: OMAP5: Add bandgap DT entry ARM: dts: AM33XX: Add pinmux configuration for CPSW to am335x EVM ARM: dts: AM33XX: Add pinmux configuration for CPSW to EVMsk ARM: dts: AM33XX: Add pinmux configuration for CPSW to beaglebone ...
