| Invensense ICS-43432-compatible MEMS microphone with I2S output. |
| |
| There are no software configuration options for this device, indeed, the only |
| host connection is the I2S interface. Apart from requirements on clock |
| frequency (460 kHz to 3.379 MHz according to the data sheet) there must be |
| 64 clock cycles in each stereo output frame; 24 of the 32 available bits |
| contain audio data. A hardware pin determines if the device outputs data |
| on the left or right channel of the I2S frame. |
| |
| Required properties: |
| - compatible: should be one of the following. |
| "invensense,ics43432": For the Invensense ICS43432 |
| "cui,cmm-4030d-261": For the CUI CMM-4030D-261-I2S-TR |
| |
| Example: |
| |
| ics43432: ics43432 { |
| compatible = "invensense,ics43432"; |
| }; |
