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:
ID Name

0: PULSE_DUMMY
1: I2C
2: NAND_NFSC
3: SDMMC1
4: SDMMC2
5: SDMMC3
6: SPI1
7: SPI2
8: SPI3
9: UART1
10: UART2
11: UART3
12: GPIO1
13: GPIO2
14: GPIO3
15: KEYPAD
16: TIMER
17: TIMEROS
18: COMREG0
19: COMREG1
20: USB
21: DMC
22: DMA
23: CAMERA
24: GOUDA
25: GPU
26: VPU_JPG
27: VPU_HOST
28: VOC
29: AUIFC0
30: AUIFC1
31: L2CC
Example:
apb@20800000 {
compatible = "simple-bus";
...
intc: interrupt-controller@0 {
compatible = "rda,8810pl-intc";
reg = <0x0 0x1000>;
interrupt-controller;
#interrupt-cells = <2>;
};
};
