+* 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";

+
+* 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>;
+       };
+
+* Serial Interface Block RAM(SIRAM)
+
+store the routing entries of SI
+
+Required properties:
+- compatible : should be "fsl,<chip>-qe-siram". For t1040, must contain
+  "fsl,t1040-qe-siram".
+- reg : Address range of SI RAM.
+
+Example:
+
+       siram1: siram@1000 {
+               compatible = "fsl,t1040-qe-siram";
+               reg = <0x1000 0x800>;
