1Amazon's Annapurna Labs Fabric Interrupt Controller 2 3Required properties: 4 5- compatible: should be "amazon,al-fic" 6- reg: physical base address and size of the registers 7- interrupt-controller: identifies the node as an interrupt controller 8- #interrupt-cells : must be 2. Specifies the number of cells needed to encode 9 an interrupt source. Supported trigger types are low-to-high edge 10 triggered and active high level-sensitive. 11- interrupts: describes which input line in the interrupt parent, this 12 fic's output is connected to. This field property depends on the parent's 13 binding 14 15Please refer to interrupts.txt in this directory for details of the common 16Interrupt Controllers bindings used by client devices. 17 18Example: 19 20amazon_fic: interrupt-controller@fd8a8500 { 21 compatible = "amazon,al-fic"; 22 interrupt-controller; 23 #interrupt-cells = <2>; 24 reg = <0x0 0xfd8a8500 0x0 0x1000>; 25 interrupt-parent = <&gic>; 26 interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>; 27}; 28
