* Marvell Kirkwood SoC pinctrl driver for mpp

Please refer to marvell,mvebu-pinctrl.txt in this directory for common binding
part and usage.

Required properties:
- compatible: "marvell,88f6180-pinctrl",
              "marvell,88f6190-pinctrl", "marvell,88f6192-pinctrl",
              "marvell,88f6281-pinctrl", "marvell,88f6282-pinctrl"
              "marvell,98dx4122-pinctrl"
- reg: register specifier of MPP registers

This driver supports all kirkwood variants, i.e. 88f6180, 88f619x, and 88f628x.
It also support the 88f6281-based variant in the 98dx412x Bobcat SoCs.

Available mpp pins/groups and functions:
Note: brackets (x) are not part of the mpp name for marvell,function and given
only for more detailed description in this document.
