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 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 PEB2466 codec also supports 28 gpios (signaling pins). allOf: - $ref: /schemas/spi/spi-peripheral-props.yaml - $ref: dai-common.yaml# properties: compatible: const: infineon,peb2466 reg: description: SPI device address. maxItems: 1 clocks: items: - description: Master clock clock-names: items: - const: mclk spi-max-frequency: maximum: 8192000 reset-gpios: description: GPIO used to reset the device. maxItems: 1 firmware-name: $ref: /schemas/types.yaml#/definitions/string description: Filters coefficients file to load.
