| 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: | |
