-Synopsys DesignWare APB interrupt controller (dw_apb_ictl)
-
-Synopsys DesignWare provides interrupt controller IP for APB known as
-dw_apb_ictl. The IP is used as secondary interrupt controller in some SoCs with
-APB bus, e.g. Marvell Armada 1500. It can also be used as primary interrupt
-controller in some SoCs, e.g. Hisilicon SD5203.
-
-Required properties:
-- compatible: shall be "snps,dw-apb-ictl"
-- reg: physical base address of the controller and length of memory mapped
- region starting with ENABLE_LOW register
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: number of cells to encode an interrupt-specifier, shall be 1
-
-Additional required property when it's used as secondary interrupt controller:
-- interrupts: interrupt reference to primary interrupt controller
-
-The interrupt sources map to the corresponding bits in the interrupt
-registers, i.e.
-- 0 maps to bit 0 of low interrupts,
-- 1 maps to bit 1 of low interrupts,
-- 32 maps to bit 0 of high interrupts,
-- 33 maps to bit 1 of high interrupts,
-- (optional) fast interrupts start at 64.

-Example:
- /* dw_apb_ictl is used as secondary interrupt controller */
- aic: interrupt-controller@3000 {
- compatible = "snps,dw-apb-ictl";
- reg = <0x3000 0xc00>;
- interrupt-controller;
- #interrupt-cells = <1>;
- interrupt-parent = <&gic>;
- interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
- };
-
- /* dw_apb_ictl is used as primary interrupt controller */
- vic: interrupt-controller@10130000 {
- compatible = "snps,dw-apb-ictl";
- reg = <0x10130000 0x1000>;
- interrupt-controller;
- #interrupt-cells = <1>;
