3Required properties:
4
5- compatible: must be "renesas,irqc-<soctype>" or "renesas,intc-ex-<soctype>",

11 - "renesas,irqc-r8a7745" (RZ/G1E)
12 - "renesas,irqc-r8a77470" (RZ/G1C)
13 - "renesas,irqc-r8a7790" (R-Car H2)
14 - "renesas,irqc-r8a7791" (R-Car M2-W)
15 - "renesas,irqc-r8a7792" (R-Car V2H)
16 - "renesas,irqc-r8a7793" (R-Car M2-N)
17 - "renesas,irqc-r8a7794" (R-Car E2)
18 - "renesas,intc-ex-r8a774a1" (RZ/G2M)
19 - "renesas,intc-ex-r8a774c0" (RZ/G2E)
20 - "renesas,intc-ex-r8a7795" (R-Car H3)
21 - "renesas,intc-ex-r8a7796" (R-Car M3-W)
22 - "renesas,intc-ex-r8a77965" (R-Car M3-N)
23 - "renesas,intc-ex-r8a77970" (R-Car V3M)
24 - "renesas,intc-ex-r8a77980" (R-Car V3H)
25 - "renesas,intc-ex-r8a77990" (R-Car E3)
26 - "renesas,intc-ex-r8a77995" (R-Car D3)
27- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
28 interrupts.txt in this directory
29- clocks: Must contain a reference to the functional clock.
