+BMan Portal Node
+
+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@ff4000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "simple-bus";
