1 Amazon's Annapurna Labs Fabric Interrupt Controller
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.
9 First cell defines the index of the interrupt within the controller.
10 Second cell is used to specify the trigger type and must be one of the
12 - bits[3:0] trigger type and level flags
13 1 = low-to-high edge triggered
14 4 = active high level-sensitive
15 - interrupt-parent: specifies the parent interrupt controller.
16 - interrupts: describes which input line in the interrupt parent, this
17 fic's output is connected to. This field property depends on the parent's
