DT bindings for the R-Mobile/R-Car interrupt controller
|
|
|
|
Required properties:
|
|
|
|
- compatible: has to be "renesas,irqc-<soctype>", "renesas,irqc" as fallback.
|
|
Examples with soctypes are:
|
|
- "renesas,irqc-r8a73a4" (R-Mobile APE6)
|
|
- "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)
|
|
- #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

Example:
|
|
|
|
irqc0: interrupt-controller@e61c0000 {
|
|
compatible = "renesas,irqc-r8a7790", "renesas,irqc";
|
|
#interrupt-cells = <2>;

reg = <0 0xe61c0000 0 0x200>;

<0 1 IRQ_TYPE_LEVEL_HIGH>,
