Subject[PATCH] dt-bindings: irqchip: renesas-rza1-irqc: Convert to json-schema
Date
Convert the Renesas RZ/A1 Interrupt Controller Device Tree binding
documentation to json-schema.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
Validation depends on "[PATCH dt-schema] Fix interrupt controllers with
interrupt-map".

-DT bindings for the Renesas RZ/A1 Interrupt Controller
-
-The RZ/A1 Interrupt Controller is a front-end for the GIC found on Renesas
-RZ/A1 and RZ/A2 SoCs:
- - IRQ sense select for 8 external interrupts, 1:1-mapped to 8 GIC SPI
- interrupts,
- - NMI edge select.
-
-Required properties:
- - compatible: Must be "renesas,<soctype>-irqc", and "renesas,rza1-irqc" as
- fallback.
- Examples with soctypes are:
- - "renesas,r7s72100-irqc" (RZ/A1H)
- - "renesas,r7s9210-irqc" (RZ/A2M)
- - #interrupt-cells: Must be 2 (an interrupt index and flags, as defined
- in interrupts.txt in this directory)
- - #address-cells: Must be zero
- - interrupt-controller: Marks the device as an interrupt controller
- - reg: Base address and length of the memory resource used by the interrupt
- controller
- - interrupt-map: Specifies the mapping from external interrupts to GIC
- interrupts
- - interrupt-map-mask: Must be <7 0>
-
-Example:
-
- irqc: interrupt-controller@fcfef800 {
- compatible = "renesas,r7s72100-irqc", "renesas,rza1-irqc";
- #interrupt-cells = <2>;
- #address-cells = <0>;
- interrupt-controller;
- reg = <0xfcfef800 0x6>;
- interrupt-map =
- <0 0 &gic GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>,
- <1 0 &gic GIC_SPI 1 IRQ_TYPE_LEVEL_HIGH>,
- <2 0 &gic GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>,
