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.
