The codec uses one 8bit time-slot per channel.20 'dai-tdm-tdm-slot-with' must be set to 8.21 22 The PEB2466 codec also supports 28 gpios (signaling pins).23 24allOf:25 - $ref: /schemas/spi/spi-peripheral-props.yaml26 - $ref: dai-common.yaml#27 28properties:29 compatible:30 const: infineon,peb246631 32 reg:33 description:34 SPI device address.35 maxItems: 136 37 clocks:38 items:39 - description: Master clock40 41 clock-names:42 items:43 - const: mclk44 45 spi-max-frequency:46 maximum: 819200047 48 reset-gpios:49 description:50 GPIO used to reset the device.51 maxItems: 152 53 firmware-name:54 maxItems: 155 description:56 Filters coefficients file to load.
