| 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: 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 | |
| 15 | Example: |
| 16 | |
| 17 | ics43432: ics43432 { |
| 18 | compatible = "invensense,ics43432"; |
| 19 | }; |
