374b5150cSTalel ShenharRequired properties:
474b5150cSTalel Shenhar
574b5150cSTalel Shenhar- compatible: should be "amazon,al-fic"
674b5150cSTalel Shenhar- reg: physical base address and size of the registers
774b5150cSTalel Shenhar- interrupt-controller: identifies the node as an interrupt controller
8*50ce73cfSTalel Shenhar- #interrupt-cells : must be 2. Specifies the number of cells needed to encode
9*50ce73cfSTalel Shenhar  an interrupt source. Supported trigger types are low-to-high edge
10*50ce73cfSTalel Shenhar  triggered and active high level-sensitive.
1174b5150cSTalel Shenhar- interrupts: describes which input line in the interrupt parent, this
1274b5150cSTalel Shenhar  fic's output is connected to. This field property depends on the parent's
