[ASOC][tlv320aic3110] Error resetting registers and error 16 (device or resource busy)

Question

I am having an issue with the tlv320aic3110 codec. I get these two errors during boot up in my embedded device:

[   10.079068] tlv320aic31xx-codec 0-0018: Unable to sync registers 0x1d-0x1d. -6
[   10.161668] tlv320aic31xx-codec 0-0018: Failed to restore cache: -6

According to the datasheet, 0x1d can be "Table 7-69. Page 0 / Register 29 (0x1D): Codec Interface Control 2" or "Table 7-136. Page 1 / Register 1 (0x01) Through Page 1 / Register 29 (0x1D): Reserved".

After about a minute, there are also these errors:

[   66.858820] tlv320aic31xx-codec 0-0018: ASoC: error at snd_soc_component_update_bits on tlv320aic31xx-codec.0-0018: -16

And finally, after suspend/resume, I get these last errors:

I have been trying to find a solution for a few days but I haven't been able to find anything important. Is there anything I could do to maybe get closer to the root cause of these errors? Has anyone seen something like this before?

Kernel version is 5.15.131.

I believe the problem is likely to be in the device tree, but I have no idea what I could change to fix it.

Let me know if you need any other information from me that might help.

Thanks in advance!
