Amazon's Annapurna Labs Fabric Interrupt Controller
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "amazon,al-fic"
|
|
- reg: physical base address and size of the registers
|
|
- interrupt-controller: identifies the node as an interrupt controller
|
|
- #interrupt-cells : must be 2. Specifies the number of cells needed to encode
|
|
an interrupt source. Supported trigger types are low-to-high edge
|
|
triggered and active high level-sensitive.
|
|
- interrupts: describes which input line in the interrupt parent, this
|
|
fic's output is connected to. This field property depends on the parent's
|
|
binding
|
|

|
compatible = "amazon,al-fic";
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
|
|
reg = <0x0 0xfd8a8500 0x0 0x1000>;
|
|
interrupt-parent = <&gic>;
|
|
interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>;
