+	- QMan Portal
+	- Example
+
+QMan Portal Node
+
+Portals are memory mapped interfaces to QMan that allow low-latency, lock-less
+interaction by software running on processor cores, accelerators and network
+interfaces with the QMan
+
+PROPERTIES
+
+- compatible
+	Usage:		Required
+	Value type:	<stringlist>
+	Definition:	Must include "fsl,qman-portal-<hardware revision>"
+			May include "fsl,<SoC>-qman-portal" or "fsl,qman-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
+
+- interrupts
+	Usage:		Required
+	Value type:	<prop-encoded-array>
+	Definition:	Standard property
+
+- fsl,liodn
+	Usage:		See pamu.txt
+	Value type:	<prop-encoded-array>
+	Definition:	Two LIODN(s). DQRR LIODN (DLIODN) and Frame LIODN
+			(FLIODN)
+
+- fsl,iommu-parent
+	Usage:		See pamu.txt
+	Value type:	<phandle>
+	Definition:	PAMU property used for dynamic LIODN assignment
+
+	For additional details about the PAMU/LIODN binding(s) see pamu.txt
+
+- cell-index
+	Usage:		Required
+	Value type:	<u32>
+	Definition:	The hardware index of the channel. This can also be
+			determined by dividing any of the channel's 8 work queue
+			IDs by 8
+
+In addition to these properties the qman-portals should have sub-nodes to
+represent the HW devices/portals that are connected to the software portal
+described here
+
+The currently supported sub-nodes are:
+	* fman0
+	* fman1
+	* pme
+	* crypto
+
+These subnodes should have the following properties:
+
+- fsl,liodn
+	Usage:		See pamu.txt
+	Value type:	<prop-encoded-array>
+	Definition:	PAMU property used for static LIODN assignment
+
+- fsl,iommu-parent
+	Usage:		See pamu.txt
+	Value type:	<phandle>
+	Definition:	PAMU property used for dynamic LIODN assignment
+
+- dev-handle
+	Usage:		Required
+	Value type:	<phandle>
+	Definition:	The phandle to the particular hardware device that this
+			portal is connected to.
+
+EXAMPLE
+
+The example below shows a (P4080) QMan portals container/bus node with two portals
+
+	qman-portals@ff4200000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		compatible = "simple-bus";
+		ranges = <0 0xf 0xf4200000 0x200000>;
+
+		qman-portal@0 {
+			compatible = "fsl,qman-portal-1.2.0", "fsl,qman-portal";
+			reg = <0 0x4000>, <0x100000 0x1000>;
+			interrupts = <104 2 0 0>;
+			fsl,liodn = <1 2>;
+			fsl,qman-channel-id = <0>;
+
+			fman0 {
+				fsl,liodn = <0x21>;
+				dev-handle = <&fman0>;
+			};
+			fman1 {
+				fsl,liodn = <0xa1>;
+				dev-handle = <&fman1>;
+			};
+			crypto {
+				fsl,liodn = <0x41 0x66>;
+				dev-handle = <&crypto>;
+			};
+		};
+		qman-portal@4000 {
+			compatible = "fsl,qman-portal-1.2.0", "fsl,qman-portal";
+			reg = <0x4000 0x4000>, <0x101000 0x1000>;
+			interrupts = <106 2 0 0>;
+			fsl,liodn = <3 4>;
+			cell-index = <1>;
+
+			fman0 {
+				fsl,liodn = <0x22>;
+				dev-handle = <&fman0>;
+			};
+			fman1 {
+				fsl,liodn = <0xa2>;
+				dev-handle = <&fman1>;
+			};
+			crypto {
+				fsl,liodn = <0x42 0x67>;
+				dev-handle = <&crypto>;
+			};
+		};
+	};
