+* QE Firmware Node
+
+This node defines a firmware binary that is embedded in the device tree, for
+the purpose of passing the firmware from bootloader to the kernel, or from
+the hypervisor to the guest.
+
+The firmware node itself contains the firmware binary contents, a compatible
+property, and any firmware-specific properties.  The node should be placed
+inside a QE node that needs it.  Doing so eliminates the need for a
+fsl,firmware-phandle property.  Other QE nodes that need the same firmware
+should define an fsl,firmware-phandle property that points to the firmware node
+in the first QE node.
+
+The fsl,firmware property can be specified in the DTS (possibly using incbin)
+or can be inserted by the boot loader at boot time.
+
+Required properties:
+  - compatible
+      Usage: required
+      Value type: <string>
+      Definition: A standard property.  Specify a string that indicates what
+          kind of firmware it is.  For QE, this should be "fsl,qe-firmware".
+
+   - fsl,firmware
+      Usage: required
+      Value type: <prop-encoded-array>, encoded as an array of bytes
+      Definition: A standard property.  This property contains the firmware
+          binary "blob".
+
+Example:
+	qe1@e0080000 {
+		compatible = "fsl,qe";
+		qe_firmware:qe-firmware {
+			compatible = "fsl,qe-firmware";
+			fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
+		};
+		...
+	};
+
+	qe2@e0090000 {
+		compatible = "fsl,qe";
+		fsl,firmware-phandle = <&qe_firmware>;
+		...
+	};
