Cirrus Logic CLPS711X Interrupt Controller
|
|
Required properties:
|
|
- compatible: Should be "cirrus,ep7209-intc".
|
- reg: Specifies base physical address of the registers set.
|
- interrupt-controller: Identifies the node as an interrupt controller.
|
- #interrupt-cells: Specifies the number of cells needed to encode an
|
interrupt source. The value shall be 1.
|
|
The interrupt sources are as follows:
