Pull ARM SoC device tree conversions from Arnd Bergmann: "These are device tree conversions for a number of platforms, with the intention of turning code from board files into device tree descriptions. Notable changes are: - davinci bindings for pinctrl, MTD, RTC, watchdog and i2c - nomadik bindings for all devices, removing the board files - bcm2835 bindings for mmc and i2c - tegra bindings for hdmi, keyboard, audio, as well as some updates - at91 bindings for hardware ecc and for devices on RM9200 - mxs bindings for cfa100xx - sunxi support for Miniand Hackberry board" * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (72 commits) Revert "sunxi: a10-cubieboard: Add user LEDs to the device tree" Revert "sunxi: a13-olinuxino: Add user LED to the device tree" clk: tegra: initialise parent of uart clocks ARM: tegra: remove clock-frequency properties from serial nodes clk: tegra: fix driver to match DT binding clk: tegra: local arrays should be static clk: tegra: Add missing spinlock for hclk and pclk clk: tegra: Implement locking for super clock clk: tegra: fix wrong clock index between se to sata_cold sunxi: a13-olinuxino: Add user LED to the device tree ARM: davinci: da850 DT: add support for machine reboot ARM: davinci: da850: add wdt DT node ARM: davinci: da850: add DT node for I2C0 ARM: at91: at91sam9n12: add DT parameters to enable PMECC ARM: at91: at91sam9x5: add DT parameters to enable PMECC ARM: at91: add EMAC bindings to RM9200 DT ARM: at91: add SSC bindings to RM9200 DT ARM: at91: add MMC bindings to RM9200 DT ARM: at91: Animeo IP: enable watchdog support ARM: nomadik: fix OF compilation regression ...
