AK7755 Audio CODEC

Hi All,

I implemented AK7755 audio codec on iMX6ull.

I am able to probe i2c driver, successfully map DAI with codec.

But I am getting below error and playback using aplay is not working yet,.

ak7755 0-0018: Control not supported for path LineOut Amp3 Mixer -> [NULL] -> Line Out3

[AK7755] ak7755_reg_write address = CE Data = 0B

#0: ak7755-audio

I think machine driver has got issues with audio routing and DAPM settings.

Can anyone share me any reference machine driver code that aligns more with AK7755?

Thanks

Hello kmagi,

I think your error is that you have connected the SPI lines to the ak7755, we don´t have any code or machine code to connect this device. However you can see the Linux reference manual for SPI that is fully tested.
