| 2 | |
| 3 | The interrupt controller in RDA8810PL SoC is a custom interrupt controller |
| 4 | which supports up to 32 interrupts. |
| 5 | |
| 6 | Required properties: |
| 7 | |
| 8 | - compatible: Should be "rda,8810pl-intc". |
| 9 | - reg: Specifies base physical address of the registers set. |
| 10 | - interrupt-controller: Identifies the node as an interrupt controller. |
| 11 | - #interrupt-cells: Specifies the number of cells needed to encode an |
| 12 | interrupt source. The value shall be 2. |
| 13 | |
| 14 | The interrupt sources are as follows: |
