+* Freescale QUICC Engine module (QE)
+This represents qe module that is installed on PowerQUICC II Pro.
+
+NOTE:  This is an interim binding; it should be updated to fit
+in with the CPM binding later in this document.
+
+Basically, it is a bus of devices, that could act more or less
+as a complete entity (UCC, USB etc ). All of them should be siblings on
+the "root" qe node, using the common properties from there.
+The description below applies to the qe of MPC8360 and
+more nodes and properties would be extended in the future.
+
+i) Root QE device
+
+Required properties:
+- compatible : should be "fsl,qe";
+- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
+- reg : offset and length of the device registers.
+- bus-frequency : the clock frequency for QUICC Engine.
+
+Recommended properties
+- brg-frequency : the internal clock source frequency for baud-rate
+  generators in Hz.
+
+Example:
+     qe@e0100000 {
+        #address-cells = <1>;
+        #size-cells = <1>;
+        #interrupt-cells = <2>;
+        compatible = "fsl,qe";
+        ranges = <0 e0100000 00100000>;
+        reg = <e0100000 480>;
+        brg-frequency = <0>;
+        bus-frequency = <179A7B00>;
+     }
+
+* Multi-User RAM (MURAM)
+
+Required properties:
+- compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
+- mode : the could be "host" or "slave".
+- ranges : Should be defined as specified in 1) to describe the
+   translation of MURAM addresses.
+- data-only : sub-node which defines the address area under MURAM
+   bus that can be allocated as data/parameter
+
+Example:
+
+     muram@10000 {
+        compatible = "fsl,qe-muram", "fsl,cpm-muram";
+        ranges = <0 00010000 0000c000>;
+
+        data-only@0{
+                compatible = "fsl,qe-muram-data",
+                             "fsl,cpm-muram-data";
+                reg = <0 c000>;
+        };
+     };
