So 'interrupts' should be: interrupts: oneOf: - maxItems: 1 - description: port F has dedicated irq line for each gpio line maxItems: 8 > + minItems: 8 > + maxItems: 8 > + description: port F has dedicated irq line for each gpio line. > + > +required: > + - compatible > + - reg > + - gpio-controller > + - "#gpio-cells" > + > +additionalProperties: false > + > +examples: > + - | > + gpio0: gpio@80840000 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "A"; > + reg = <0x80840000 0x04>, > + <0x80840010 0x04>, > + <0x80840090 0x1c>; > + reg-names = "data", "dir", "intr"; > + gpio-controller; > + #gpio-cells = <2>; > + interrupt-controller; > + interrupt-parent = <&vic1>; > + interrupts = <27>; > + }; > + > + gpio1: gpio@80840004 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "B"; > + reg = <0x80840004 0x04>, > + <0x80840014 0x04>, > + <0x808400ac 0x1c>; > + reg-names = "data", "dir", "intr"; > + gpio-controller; > + #gpio-cells = <2>; > + interrupt-controller; > + interrupt-parent = <&vic1>; > + interrupts = <27>; > + }; > + > + gpio2: gpio@80840008 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "C"; > + reg = <0x80840008 0x04>, > + <0x80840018 0x04>; > + reg-names = "data", "dir"; > + gpio-controller; > + #gpio-cells = <2>; > + }; > + > + gpio3: gpio@8084000c { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "D"; > + reg = <0x8084000c 0x04>, > + <0x8084001c 0x04>; > + reg-names = "data", "dir"; > + gpio-controller; > + #gpio-cells = <2>; > + }; > + > + gpio4: gpio@80840020 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "E"; > + reg = <0x80840020 0x04>, > + <0x80840024 0x04>; > + reg-names = "data", "dir"; > + gpio-controller; > + #gpio-cells = <2>; > + }; > + > + gpio5: gpio@80840030 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "F"; > + reg = <0x80840030 0x04>, > + <0x80840034 0x04>, > + <0x8084004c 0x1c>; > + reg-names = "data", "dir", "intr"; > + gpio-controller; > + #gpio-cells = <2>; > + interrupt-controller; > + interrupts-extended = <&vic0 19>, <&vic0 20>, > + <&vic0 21>, <&vic0 22>, > + <&vic1 15>, <&vic1 16>, > + <&vic1 17>, <&vic1 18>; > + }; > + > + gpio6: gpio@80840038 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "G"; > + reg = <0x80840038 0x04>, > + <0x8084003c 0x04>; > + reg-names = "data", "dir"; > + gpio-controller; > + #gpio-cells = <2>; > + }; > + > + gpio7: gpio@80840040 { > + compatible = "cirrus,ep9301-gpio"; > + chip-label = "H"; > + reg = <0x80840040 0x04>, > + <0x80840044 0x04>; > + reg-names = "data", "dir"; > + gpio-controller; > + #gpio-cells = <2>; > + }; > + > +... > -- > 2.39.2 >
