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.

+ST-Ericsson U300 Device Tree Bindings
+
+For various board the "board" node may contain specific properties
+that pertain to this particular board, such as board-specific GPIOs
+or board power regulator supplies.
+
+Required root node property:
+
+compatible="stericsson,u300";
+
+Required node: syscon
+This contains the system controller.
+- compatible: must be "stericsson,u300-syscon".
+- reg: the base address and size of the system controller.
+
+Boards with the U300 SoC include:
+
+S365 "Small Board U365":
+
+Required node: s365
+This contains the board-specific information.
+- compatible: must be "stericsson,s365".
+- vana15-supply: the regulator supplying the 1.5V to drive the
+  board.
+- syscon: a pointer to the syscon node so we can acccess the
+  syscon registers to set the board as self-powered.
+
+Example:
+
