+* 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>;
+ reg = <0x80 0x80>;
+ interrupts = <95 2 0 0 94 2 0 0>;

+
+* 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 : must be "fsl,<chip>-qe-si". For t1040, must contain
+ "fsl,t1040-qe-si".
+- reg : Address range of SI register set.
+
+Example:
+
+ si1: si@700 {
+ compatible = "fsl,t1040-qe-si";
+ reg = <0x700 0x80>;

+Required properties:
+- compatible : should be "fsl,<chip>-qe-siram". For t1040, must contain

+ siram1: siram@1000 {
