* Marvell 98dx3236 pinctrl driver for mpp

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

Required properties:
- compatible: "marvell,98dx3236-pinctrl" or "marvell,98dx4251-pinctrl"
- reg: register specifier of MPP registers

This driver supports all 98dx3236, 98dx3336 and 98dx4251 variants
