The time-slots used by the codec must be set and so, the properties 'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and 'dai-tdm-slot-rx-mask' must be present in the ALSA sound card node for sub-nodes that involve the codec. The codec uses one 8bit time-slot per channel. 'dai-tdm-tdm-slot-with' must be set to 8. The IDT821034 codec also supports 5 gpios (SLIC signals) per channel. allOf: - $ref: /schemas/spi/spi-peripheral-props.yaml# - $ref: dai-common.yaml# properties: compatible: const: renesas,idt821034 reg: description: SPI device address. maxItems: 1 spi-max-frequency: maximum: 8192000 spi-cpha: true '#sound-dai-cells': const: 0 '#gpio-cells': const: 2 gpio-controller: true required: - compatible - reg - spi-cpha - '#sound-dai-cells' - gpio-controller - '#gpio-cells' unevaluatedProperties: false examples: - | spi { #address-cells = <1>; #size-cells = <0>; audio-codec@0 { compatible = "renesas,idt821034"; reg = <0>; spi-max-frequency = <8192000>; spi-cpha; #sound-dai-cells = <0>; gpio-controller; #gpio-cells = <2>; }; };
