1DT bindings for the R-Mobile/R-Car/RZ/G interrupt controller
2
3Required properties:
4
5- compatible: has to be "renesas,irqc-<soctype>", "renesas,irqc" as fallback.
6 Examples with soctypes are:
7 - "renesas,irqc-r8a73a4" (R-Mobile APE6)
8 - "renesas,irqc-r8a7743" (RZ/G1M)
9 - "renesas,irqc-r8a7745" (RZ/G1E)
10 - "renesas,irqc-r8a7790" (R-Car H2)
11 - "renesas,irqc-r8a7791" (R-Car M2-W)
12 - "renesas,irqc-r8a7792" (R-Car V2H)
13 - "renesas,irqc-r8a7793" (R-Car M2-N)
14 - "renesas,irqc-r8a7794" (R-Car E2)
15 - "renesas,intc-ex-r8a7795" (R-Car H3)
16 - "renesas,intc-ex-r8a7796" (R-Car M3-W)
17 - "renesas,intc-ex-r8a77970" (R-Car V3M)
18 - "renesas,intc-ex-r8a77995" (R-Car D3)
19- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
20 interrupts.txt in this directory
21- clocks: Must contain a reference to the functional clock.
22
23Optional properties:
24
25- any properties, listed in interrupts.txt, and any standard resource allocation
26 properties

30 irqc0: interrupt-controller@e61c0000 {
31 compatible = "renesas,irqc-r8a7790", "renesas,irqc";
32 #interrupt-cells = <2>;
33 interrupt-controller;
34 reg = <0 0xe61c0000 0 0x200>;
35 interrupts = <0 0 IRQ_TYPE_LEVEL_HIGH>,
36 <0 1 IRQ_TYPE_LEVEL_HIGH>,
37 <0 2 IRQ_TYPE_LEVEL_HIGH>,
38 <0 3 IRQ_TYPE_LEVEL_HIGH>;
39 clocks = <&mstp4_clks R8A7790_CLK_IRQC>;
40 };
