Each pair serves 32 GPIOs. The VF610 has 5 instances of 15 each, and each PORT module has its own interrupt. 16 17 Note: Each GPIO port should have an alias correctly numbered in "aliases" 18 node. 19 20properties: 21 compatible: 22 oneOf: 23 - const: fsl,vf610-gpio 24 - items: 25 - const: fsl,imx7ulp-gpio 26 - const: fsl,vf610-gpio 27 28 reg: 29 description: The first reg tuple represents the PORT module, the second tuple 30 represents the GPIO module. 31 maxItems: 2 32 33 interrupts: 34 maxItems: 1 35 36 interrupt-controller: true 37 38 "#interrupt-cells": 39 const: 2 40 41 "#gpio-cells": 42 const: 2 43 44 gpio-controller: true 45 46 clocks: 47 items: 48 - description: SoC GPIO clock 49 - description: SoC PORT clock 50 51 clock-names: 52 items: 53 - const: gpio 54 - const: port 55 56 gpio-ranges: 57 maxItems: 1 58 59required: 60 - compatible 61 - reg 62 - interrupts 63 - interrupt-controller 64 - "#interrupt-cells" 65 - "#gpio-cells" 66 - gpio-controller 67 68additionalProperties: false 69 70examples: 71 - | 72 #include <dt-bindings/interrupt-controller/arm-gic.h> 73 74 gpio1: gpio@40049000 { 75 compatible = "fsl,vf610-gpio"; 76 reg = <0x40049000 0x1000>, <0x400ff000 0x40>; 77 interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>; 78 gpio-controller; 79 #gpio-cells = <2>; 80 interrupt-controller; 81 #interrupt-cells = <2>; 82 gpio-ranges = <&iomuxc 0 0 32>; 83 }; 84
