+* Marvell Armada 39x 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,88f6920-pinctrl", "marvell,88f6928-pinctrl"
+ depending on the specific variant of the SoC being used.
+- reg: register specifier of MPP registers
+
+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.

This commit adds the Device Tree binding documentation to describe the pin-muxing controller of the Marvell Armada 39x processors. Two variants are supported for the moment: the 88F6920 (Armada 390) and 88F6928 (Armada 398).
