-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

+
+description: |
+ The ICS-43432 and compatible MEMS microphones output audio over an I2S
+ interface and require no software configuration. The only host connection
+ is the I2S bus. The microphone requires an I2S clock frequency between
+ 460 kHz and 3.379 MHz and 64 clock cycles per stereo frame. Each frame
+ contains 32-bit slots per channel, with 24 bits carrying audio data.
+ A hardware pin determines whether the microphone outputs audio on the
+ left or right channel of the I2S frame.

A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
