RDA Micro RDA8810PL Interrupt Controller
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:
