+* Interrupt Controller (IC)
+
+Required properties:
+- compatible : should be "fsl,qe-ic".
+- reg : Address range of IC register set.
+- interrupts : interrupts generated by the device.
+- interrupt-controller : this device is a interrupt controller.
+
+Example:
+
+	qeic: interrupt-controller@80 {
+		interrupt-controller;
+		compatible = "fsl,qe-ic";
+		#address-cells = <0>;
+		#interrupt-cells = <1>;

+* Serial Interface Block (SI)
+
+The SI manages the routing of eight TDM lines to the QE block serial drivers
+, the MCC and the UCCs, for receive and transmit.

+Required properties:
+- compatible : should be "fsl,t1040-qe-si".
+- reg : Address range of SI register set.
