Although it is not the reason for your problem, but you mentioned first that the codec has the external frequency of 24MHz. Here is written only 12:
ti,codec-clock-rate = <12000000>;

Hi,

I also tried setting ti,codec-clock-rate = <24000000>; then also same errors.

I am failing in defining regulators for TLV320AIC32X4 driver in Device tree, it requires ldoin, iov, dv, av. Following is the errors coming in dmesg.

[   16.607195] 2-0018 supply iov not found, using dummy regulator

[Maxim Podbereznyy]

I think these regulators are not necessary because you supply them in hardware anyway. Using dummy regulators is sufficient.

These are the problems to solve:

[   15.986046] tlv320aic32x4 2-0018: Failed getting the mclk. The current implementation does not support the usage of this codec without mclk

..

[   16.619921] ERROR: could not get clock /sound:mclk(0)

I have used this codec with imx6 and dm3730 without any issues but a kernels used were 3.0.15 and 3.2. Can't help you with DTC config

I have solved the above errors & commented out aic32x4_setup_regulators function. after these changes following errors are coming

hdmi-hifi? You should disable it

[Dileep]

Hi,

I disable hdmi-hifi & enabled tlv320aic32x4-hifi. Now the card is detected.

How did you solve the failed gettin mclk error?

[Vidhya Shree]

Hii all,
Did any one solve this error.
Even I am not getting MCLK and BCLK.
