+* 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 at 80 {
+ interrupt-controller;

+* 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.

+Example:
+
+ si1: si at 700 {
