+* 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>;
+ ...
+ };
