+Coherency fabric
+----------------
+Available on Marvell SOCs: Armada 370, Armada 375, Armada 38x and Armada XP
+
+Required properties:
+
+- compatible: the possible values are:
+
+ * "marvell,coherency-fabric", to be used for the coherency fabric of
+   the Armada 370 and Armada XP.
+
+ * "marvell,armada-375-coherency-fabric", for the Armada 375 coherency
+   fabric.
+
+ * "marvell,armada-380-coherency-fabric", for the Armada 38x coherency
+   fabric.
+
+- reg: Should contain coherency fabric registers location and
+  length.
+
+ * For "marvell,coherency-fabric", the first pair for the coherency
+   fabric registers, second pair for the per-CPU fabric registers.
+
+ * For "marvell,armada-375-coherency-fabric", only one pair is needed
+   for the per-CPU fabric registers.
+
+ * For "marvell,armada-380-coherency-fabric", only one pair is needed
+   for the per-CPU fabric registers.
+
+Optional properties:
+
+- broken-idle: boolean to set when the Idle mode is not supported by the
+  hardware.
+
+Examples:
+
+coherency-fabric@d0020200 {
+	compatible = "marvell,coherency-fabric";
+	reg = <0xd0020200 0xb0>,
+		<0xd0021810 0x1c>;
+
+};
+
+coherency-fabric@21810 {
+	compatible = "marvell,armada-375-coherency-fabric";
+	reg = <0x21810 0x1c>;
+};
