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.

2 | |||
3 | For various board the "board" node may contain specific properties | ||
4 | that pertain to this particular board, such as board-specific GPIOs | ||
5 | or board power regulator supplies. | ||
6 | |||
7 | Required root node property: | ||
8 | |||
9 | compatible="stericsson,u300"; | ||
10 | |||
11 | Required node: syscon | ||
12 | This contains the system controller. | ||
13 | - compatible: must be "stericsson,u300-syscon". | ||
14 | - reg: the base address and size of the system controller. | ||
15 | |||
16 | Boards with the U300 SoC include: | ||
17 | |||
18 | S365 "Small Board U365": | ||
19 | |||
20 | Required node: s365 | ||
21 | This contains the board-specific information. | ||
22 | - compatible: must be "stericsson,s365". | ||
23 | - vana15-supply: the regulator supplying the 1.5V to drive the | ||
24 | board. | ||
25 | - syscon: a pointer to the syscon node so we can acccess the | ||
26 | syscon registers to set the board as self-powered. | ||
