1Invensense ICS-43432-compatible MEMS microphone with I2S output. 2 3There are no software configuration options for this device, indeed, the only 4host connection is the I2S interface. Apart from requirements on clock 5frequency (460 kHz to 3.379 MHz according to the data sheet) there must be 664 clock cycles in each stereo output frame; 24 of the 32 available bits 7contain audio data. A hardware pin determines if the device outputs data 8on the left or right channel of the I2S frame. 9 10Required properties: 11 - compatible: should be one of the following. 12 "invensense,ics43432": For the Invensense ICS43432 13 "cui,cmm-4030d-261": For the CUI CMM-4030D-261-I2S-TR 14 15Example: 16 17 ics43432: ics43432 { 18 compatible = "invensense,ics43432"; 19 };
