RDA Micro RDA8810PL Interrupt Controller
|
||
|
|
|
||
|
|
The interrupt controller in RDA8810PL SoC is a custom interrupt controller
|
||
|
|
which supports up to 32 interrupts.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible: Should be "rda,8810pl-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 2.
|
||
|
|
|
||
|
|
The interrupt sources are as follows:
