+Marvell Dove Platforms Device Tree Bindings
+-----------------------------------------------
+
+Boards with a Marvell Dove SoC shall have the following properties:
+
+Required root node property:
+- compatible: must contain "marvell,dove";
+
+* Global Configuration registers
+
+Global Configuration registers of Dove SoC are shared by a syscon node.
+
+Required properties:
+- compatible: must contain "marvell,dove-global-config" and "syscon".
+- reg: base address and size of the Global Configuration registers.
+
+Example:
+
+gconf: global-config at e802c {
+	compatible = "marvell,dove-global-config", "syscon";
+	reg = <0xe802c 0x14>;
