- The Awinic AW883XX is an I2S/TDM input, high efficiency
- digital Smart K audio amplifier with an integrated 10.25V
- smart boost convert.

You also need here description
- sound-channel:
- maxItems: 1
What's this? Does not look like a standard property. You need type and description (and sometimes also vendor prefix...).
- sound-name-prefix: true

- compatible

- sound-channel

Node names should be generic, so codec or amplifier https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetre...
compatible = "awinic,aw883xx_smartpa";reg = <0x34>;reset-gpio = <&ap_gpio 92 0>;
irq-gpio = <&ap_gpio 93 0>;
Use defines for flags.
sound-channel = <0>;};- };
