Merge tag 'u300-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/soc
From Linus Walleij: Device Tree and Multiplatform support for U300: - Add devicetree support to timer, pinctrl (probe), I2C block, watchdog, DMA controller and clocks. - Piecewise add a device tree containing all peripherals. - Delete the ATAG boot path. - Delete redundant platform data and board files. - Convert to multiplatform. * tag 'u300-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: (40 commits) ARM: u300: switch to using syscon regmap for board ARM: u300: Update MMC configs for u300 defconfig spi: pl022: use DMA by default when probing from DT pinctrl: get rid of all platform data for coh901 ARM: u300: convert MMC/SD clock to device tree ARM: u300: move the gated system controller clocks to DT i2c: stu300: do not request a specific clock name clk: move the U300 fixed and fixed-factor to DT ARM: u300: remove register definition file ARM: u300: add syscon node ARM: u300 use module_spi_driver to register driver ARM: u300: delete remnant machine headers ARM: u300: convert to multiplatform ARM: u300: localize <mach/u300-regs.h> ARM: u300: delete <mach/irqs.h> ARM: u300: delete <mach/hardware.h> ARM: u300: push down syscon registers ARM: u300: remove deps from debug macro ARM: u300: move debugmacro to debug includes ARM: u300: delete all static board data ...
