Hello,
I'm a beginner in writing a .dts file for the audio codec (MAX98090), and although I faced many challenges in writing a .dts file, I was finally nearing completion, but could not complete it. I need your help in completing the code as I have none of them to guide me through this.
I'm not able to hear any sound in the speaker or in the headphones while playing the audio through the GPIO I2S interface of the RPi4.
When I checked using the logic analyzer, it showed that the RPi4 was capturing the audio, although tried configuring the codec as master and RPi4 as the slave, it didn't work.
Kindly help me with the corrections in the .dts file.
I'm attaching the datasheet and the source file link below.

https://github.com/raspberrypi/linux/bl ... max98090.c
The max98090.dts file,The dmesg logNo other logs like "Headphone detected", etc., appear here other than this.
Please Help!![:cry:]( "Crying or Very Sad")
Your help means a lot to me...
