The controller is essentially 15 a 256 pads to 8 or 12 GIC interrupt multiplexer, with a filter block to select 16 edge or level and polarity. It does not expose all 256 mux inputs because the 17 documentation shows that the upper part is not mapped to any pad. The actual 18 number of interrupts exposed depends on the SoC. 19 20allOf: 21 - $ref: /schemas/interrupt-controller.yaml# 22 23properties: 24 compatible: 25 oneOf: 26 - const: amlogic,meson-gpio-intc 27 - items: 28 - enum: 29 - amlogic,meson8-gpio-intc 30 - amlogic,meson8b-gpio-intc 31 - amlogic,meson-gxbb-gpio-intc 32 - amlogic,meson-gxl-gpio-intc 33 - amlogic,meson-axg-gpio-intc 34 - amlogic,meson-g12a-gpio-intc 35 - amlogic,meson-sm1-gpio-intc 36 - amlogic,meson-a1-gpio-intc 37 - amlogic,meson-s4-gpio-intc 38 - amlogic,c3-gpio-intc 39 - const: amlogic,meson-gpio-intc 40 41 reg: 42 maxItems: 1 43 44 interrupt-controller: true 45 46 "#interrupt-cells": 47 const: 2 48 49 amlogic,channel-interrupts: 50 description: Array with the upstream hwirq numbers 51 minItems: 8 52 maxItems: 12 53 $ref: /schemas/types.yaml#/definitions/uint32-array 54 55required: 56 - compatible 57 - reg 58 - interrupt-controller 59 - "#interrupt-cells" 60 - amlogic,channel-interrupts 61 62additionalProperties: false 63 64examples: 65 - | 66 interrupt-controller@9880 { 67 compatible = "amlogic,meson-gxbb-gpio-intc", 68 "amlogic,meson-gpio-intc"; 69 reg = <0x9880 0x10>; 70 interrupt-controller; 71 #interrupt-cells = <2>; 72 amlogic,channel-interrupts = <64 65 66 67 68 69 70 71>; 73 }; 74
