1 | Invensense ICS-43432 MEMS microphone with I2S output. |
2 | ||
3 | There are no software configuration options for this device, indeed, the only | |
4 | host connection is the I2S interface. Apart from requirements on clock | |
5 | frequency (460 kHz to 3.379 MHz according to the data sheet) there must be | |
6 | 64 clock cycles in each stereo output frame; 24 of the 32 available bits | |
7 | contain audio data. A hardware pin determines if the device outputs data | |
8 | on the left or right channel of the I2S frame. | |
9 | ||
10 | Required properties: | |
11 | - compatible : Must be "invensense,ics43432" | |
12 | ||
13 | Example: | |
14 | ||
15 | ics43432: ics43432 { | |
16 | compatible = "invensense,ics43432"; | |
17 | }; |
