Hi igorpadykov,

I tried those register settings but no use.

i am not able to get any thing. Is there any other settings, we are getting MCLK as 24MHz we probed with DSO.

Thanks

Hi Lavanya

typical bring-up procedure is to check codec clocks with oscilloscope,

use driver sources described in attached Linux Manual Table 28-1

Stereo Codec SoC Driver Files for debugging.
