It should be 'shut-down-gpios'. Looking at the driver, it is also broken. It's passing 'shut-down-gpio' which means the GPIO core is looking for 'shut-down-gpio-gpio' or 'shut-down-gpio-gpios'. Also the standardish naming here is 'shutdown-gpios'. Given this probably never worked, we should use that. > + description: GPIO used to control the state of the device. > + > + interrupts: > + maxItems: 1 > + > + ti,imon-slot-no: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: TDM TX current sense time slot. > + > + '#sound-dai-cells': > + const: 1 > + > +required: > + - compatible > + - reg > +additionalProperties: false > + > +examples: > + - | > + #include > + i2c0 { > + #address-cells = <1>; > + #size-cells = <0>; > + codec: codec@4c { > + compatible = "ti,tas2562"; > + reg = <0x4c>; > + #sound-dai-cells = <1>; > + interrupt-parent = <&gpio1>; > + interrupts = <14>; > + > + shut-down = <&gpio1 15 0>; > + ti,imon-slot-no = <0>; > + }; > + }; > + > -- > 2.26.2 >
