Merge tag 'nmk-dt-on-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt

From Linus Walleij:
Nomadik Device Tree conversion rebased on ARM SoC cleanup branch

This patch set converts the Nomadik (mach-nomadik) to
Device Tree and delete the old board files, paving the
road for single zImage.

ST-Ericsson Nomadik Device Tree Bindings



For various board the "board" node may contain specific properties

that pertain to this particular board, such as board-specific GPIOs.



Boards with the Nomadik SoC include:



S8815 "MiniKit" manufactured by Calao Systems:



Required root node property:



compatible="calaosystems,usb-s8815";



Required node: usb-s8815



Example:



usb-s8815 {

		ethernet-gpio {

			gpios = <&gpio3 19 0x1>;

			interrupts = <19 0x1>;

			interrupt-parent = <&gpio3>;

		};

		mmcsd-gpio {

			gpios = <&gpio3 16 0x1>;

		};

};

* FSMC NAND



Required properties:

- compatible : "st,spear600-fsmc-nand"

- compatible : "st,spear600-fsmc-nand", "stericsson,fsmc-nand"

- reg : Address range of the mtd chip

- reg-names: Should contain the reg names "fsmc_regs", "nand_data", "nand_addr" and "nand_cmd"
