The controller is essentially 15f126890aSEmmanuel Vadot a 256 pads to 8 or 12 GIC interrupt multiplexer, with a filter block to select 16f126890aSEmmanuel Vadot edge or level and polarity. It does not expose all 256 mux inputs because the 17f126890aSEmmanuel Vadot documentation shows that the upper part is not mapped to any pad. The actual 18f126890aSEmmanuel Vadot number of interrupts exposed depends on the SoC. 19f126890aSEmmanuel Vadot 20f126890aSEmmanuel VadotallOf: 21f126890aSEmmanuel Vadot - $ref: /schemas/interrupt-controller.yaml# 22f126890aSEmmanuel Vadot 23f126890aSEmmanuel Vadotproperties: 24f126890aSEmmanuel Vadot compatible: 25f126890aSEmmanuel Vadot oneOf: 26f126890aSEmmanuel Vadot - const: amlogic,meson-gpio-intc 27f126890aSEmmanuel Vadot - items: 28f126890aSEmmanuel Vadot - enum: 29f126890aSEmmanuel Vadot - amlogic,meson8-gpio-intc 30f126890aSEmmanuel Vadot - amlogic,meson8b-gpio-intc 31f126890aSEmmanuel Vadot - amlogic,meson-gxbb-gpio-intc 32f126890aSEmmanuel Vadot - amlogic,meson-gxl-gpio-intc 33f126890aSEmmanuel Vadot - amlogic,meson-axg-gpio-intc 34f126890aSEmmanuel Vadot - amlogic,meson-g12a-gpio-intc 35f126890aSEmmanuel Vadot - amlogic,meson-sm1-gpio-intc 36f126890aSEmmanuel Vadot - amlogic,meson-a1-gpio-intc 37f126890aSEmmanuel Vadot - amlogic,meson-s4-gpio-intc 38aa1a8ff2SEmmanuel Vadot - amlogic,c3-gpio-intc 39*01950c46SEmmanuel Vadot - amlogic,t7-gpio-intc 40f126890aSEmmanuel Vadot - const: amlogic,meson-gpio-intc 41f126890aSEmmanuel Vadot 42f126890aSEmmanuel Vadot reg: 43f126890aSEmmanuel Vadot maxItems: 1 44f126890aSEmmanuel Vadot 45f126890aSEmmanuel Vadot interrupt-controller: true 46f126890aSEmmanuel Vadot 47f126890aSEmmanuel Vadot "#interrupt-cells": 48f126890aSEmmanuel Vadot const: 2 49f126890aSEmmanuel Vadot 50f126890aSEmmanuel Vadot amlogic,channel-interrupts: 51f126890aSEmmanuel Vadot description: Array with the upstream hwirq numbers 52f126890aSEmmanuel Vadot minItems: 8 53f126890aSEmmanuel Vadot maxItems: 12 54f126890aSEmmanuel Vadot $ref: /schemas/types.yaml#/definitions/uint32-array 55f126890aSEmmanuel Vadot 56f126890aSEmmanuel Vadotrequired: 57f126890aSEmmanuel Vadot - compatible 58f126890aSEmmanuel Vadot - reg 59f126890aSEmmanuel Vadot - interrupt-controller 60f126890aSEmmanuel Vadot - "#interrupt-cells" 61f126890aSEmmanuel Vadot - amlogic,channel-interrupts 62f126890aSEmmanuel Vadot 63f126890aSEmmanuel VadotadditionalProperties: false 64f126890aSEmmanuel Vadot 65f126890aSEmmanuel Vadotexamples: 66f126890aSEmmanuel Vadot - | 67f126890aSEmmanuel Vadot interrupt-controller@9880 { 68f126890aSEmmanuel Vadot compatible = "amlogic,meson-gxbb-gpio-intc", 69f126890aSEmmanuel Vadot "amlogic,meson-gpio-intc"; 70f126890aSEmmanuel Vadot reg = <0x9880 0x10>; 71f126890aSEmmanuel Vadot interrupt-controller; 72f126890aSEmmanuel Vadot #interrupt-cells = <2>; 73f126890aSEmmanuel Vadot amlogic,channel-interrupts = <64 65 66 67 68 69 70 71>; 74f126890aSEmmanuel Vadot }; 75
