The only host connection + is the I2S bus. The microphone requires an I2S clock frequency between + 460 kHz and 3.379 MHz and 64 clock cycles per stereo frame. Each frame + contains 32-bit slots per channel, with 24 bits carrying audio data. + A hardware pin determines whether the microphone outputs audio on the + left or right channel of the I2S frame. + +allOf: + - $ref: dai-common.yaml# + +properties: + compatible: + enum: + - invensense,ics43432 + - cui,cmm-4030d-261 + + port: + $ref: audio-graph-port.yaml# + unevaluatedProperties: false + +required: + - compatible + +unevaluatedProperties: false + +examples: + - | + ics43432: ics43432 { + compatible = "invensense,ics43432"; + + port { + endpoint { + remote-endpoint = <&i2s1_endpoint>; + dai-format = "i2s"; + }; + }; + + }; |
