* Marvell Orion 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,88f5181l-pinctrl", "marvell,88f5182-pinctrl",
              "marvell,88f5281-pinctrl"

- reg: two register areas, the first one describing the first two
  contiguous MPP registers, and the second one describing the single
  final MPP register, separated from the previous one.

Available mpp pins/groups and functions:
Note: brackets (x) are not part of the mpp name for marvell,function and given
