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.
|
|
First cell defines the index of the interrupt within the controller.
|
|
Second cell is used to specify the trigger type and must be one of the
|
|
following:
|
|
- bits[3:0] trigger type and level flags
|
|
1 = low-to-high edge triggered
|
|
4 = active high level-sensitive
|
|
- interrupt-parent: specifies the parent interrupt controller.
|
|
- 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
|
|
|
|
Example:
|
|
|
|
amazon_fic: interrupt-controller@0xfd8a8500 {
|
|
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>;
|
|
};
