1 Synopsys DesignWare APB interrupt controller (dw_apb_ictl)
3 Synopsys DesignWare provides interrupt controller IP for APB known as
4 dw_apb_ictl. The IP is used as secondary interrupt controller in some SoCs with
5 APB bus, e.g. Marvell Armada 1500.
8 - compatible: shall be "snps,dw-apb-ictl"
9 - reg: physical base address of the controller and length of memory mapped
10 region starting with ENABLE_LOW register
11 - interrupt-controller: identifies the node as an interrupt controller
12 - #interrupt-cells: number of cells to encode an interrupt-specifier, shall be 1
13 - interrupts: interrupt reference to primary interrupt controller
14 - interrupt-parent: (optional) reference specific primary interrupt controller
16 The interrupt sources map to the corresponding bits in the interrupt
18 - 0 maps to bit 0 of low interrupts,
19 - 1 maps to bit 1 of low interrupts,
20 - 32 maps to bit 0 of high interrupts,
21 - 33 maps to bit 1 of high interrupts,
22 - (optional) fast interrupts start at 64.
