* 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>;

	};



* 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>;

	};



* QE Firmware Node



This node defines a firmware binary that is embedded in the device tree, for
