* 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
