| 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. |

| 10 | Required properties: |
| 11 | - compatible : Must be "invensense,ics43432" |
| 12 | |
| 13 | Example: |
| 14 | |
| 15 | ics43432: ics43432 { |
| 16 | compatible = "invensense,ics43432"; |
| 17 | }; |
