DT bindings for the R-Mobile/R-Car/RZ/G interrupt controller
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: must be "renesas,irqc-<soctype>" or "renesas,intc-ex-<soctype>",
|
||||
and "renesas,irqc" as fallback.
|
||||
Examples with soctypes are:
|
||||
- "renesas,irqc-r8a73a4" (R-Mobile APE6)
|
||||
- "renesas,irqc-r8a7743" (RZ/G1M)
|
||||
- "renesas,irqc-r8a7744" (RZ/G1N)
|
||||
- "renesas,irqc-r8a7745" (RZ/G1E)
|
||||
- "renesas,irqc-r8a77470" (RZ/G1C)
|
||||
- "renesas,irqc-r8a7790" (R-Car H2)
|
||||
- "renesas,irqc-r8a7791" (R-Car M2-W)
|
||||
- "renesas,irqc-r8a7792" (R-Car V2H)
|
||||
- "renesas,irqc-r8a7793" (R-Car M2-N)
|
||||
- "renesas,irqc-r8a7794" (R-Car E2)
|
||||
- "renesas,intc-ex-r8a774a1" (RZ/G2M)
|
||||
- "renesas,intc-ex-r8a774c0" (RZ/G2E)
|
||||
- "renesas,intc-ex-r8a7795" (R-Car H3)
|
||||
- "renesas,intc-ex-r8a7796" (R-Car M3-W)
|
||||
- "renesas,intc-ex-r8a77965" (R-Car M3-N)
|
||||
- "renesas,intc-ex-r8a77970" (R-Car V3M)
|
||||
- "renesas,intc-ex-r8a77980" (R-Car V3H)
|
||||
- "renesas,intc-ex-r8a77990" (R-Car E3)
|
||||
- "renesas,intc-ex-r8a77995" (R-Car D3)
|
||||
- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
|
||||
interrupts.txt in this directory
|
||||
- clocks: Must contain a reference to the functional clock.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- any properties, listed in interrupts.txt, and any standard resource allocation
|
||||
properties
|
||||
|
||||
Example:
|
||||
|
||||
irqc0: interrupt-controller@e61c0000 {
|
||||
compatible = "renesas,irqc-r8a7790", "renesas,irqc";
|
||||
#interrupt-cells = <2>;
|
||||
interrupt-controller;
|
||||
reg = <0 0xe61c0000 0 0x200>;
|
||||
interrupts = <0 0 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<0 1 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<0 2 IRQ_TYPE_LEVEL_HIGH>,
|
||||
<0 3 IRQ_TYPE_LEVEL_HIGH>;
|
||||
clocks = <&mstp4_clks R8A7790_CLK_IRQC>;
