The registers of all the banks are interwoven inside one single IO range. We load one GPIO controller instance per bank. Also the GPIO controller can receive interrupts on any of the GPIOs, either edge or level. It then interrupts the CPU using GIC INT12. properties: $nodename: pattern: "^gpio@[0-9a-f]+$" compatible: const: mediatek,mt7621-gpio reg: maxItems: 1 "#gpio-cells": const: 2 gpio-controller: true gpio-ranges: true interrupt-controller: true "#interrupt-cells": const: 2 interrupts: maxItems: 1 required: - compatible - reg - "#gpio-cells" - gpio-controller - gpio-ranges - interrupt-controller - "#interrupt-cells" - interrupts additionalProperties: false examples: - | #include #include gpio@600 { compatible = "mediatek,mt7621-gpio"; reg = <0x600 0x100>; #gpio-cells = <2>; gpio-controller; gpio-ranges = <&pinctrl 0 0 95>; interrupt-controller; #interrupt-cells = <2>; interrupt-parent = <&gic>; interrupts = ; }; ...
