+
+PROPERTIES
+
+- compatible
+	Usage:		Required
+	Value type:	<stringlist>
+	Definition:	Must include "fsl,bman-portal-<hardware revision>"
+			May include "fsl,<SoC>-bman-portal" or "fsl,bman-portal"
+
+- reg
+	Usage:		Required
+	Value type:	<prop-encoded-array>
+	Definition:	Two regions. The first is the cache-enabled region of
+			the portal. The second is the cache-inhibited region of
+			the portal
+
+EXAMPLE
+
+The example below shows a (P4080) BMan portals container/bus node with two portals
+
+	bman-portals at ff4000000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		compatible = "simple-bus";
+		ranges = <0 0xf 0xf4000000 0x200000>;
+
+		bman-portal at 0 {
+			compatible = "fsl,bman-portal-1.0.0", "fsl,bman-portal";
+			reg = <0x0 0x4000 0x100000 0x1000>;
