| 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>; |
| }; |
