TLV320AIC32X4SW-LINUX: TLV320AIC32X4SW-LINUX:

Hi Aaron,

Thanks for your kindly reply.

I should update the issue latest status first, 

TLV320AIC32X4 driver code already merged, from the kernel log, I found it can't work well till now.

log snippet 1:

[    0.648491] aic32x4_i2c_probe(): aic32x4_i2c_probe

[    0.648543] of_get_named_gpiod_flags: can't parse 'reset-gpios' property of node '/soc/i2c@78b8000/tlv320aic32x4_codec@18[0]'

[    0.648563] tlv320aic32x4-codec 4-0018: Failed getting the mclk. The current implementation does not support the usage of this codec without mclk

[    0.648615] tlv320aic32x4-codec: probe of 4-0018 failed with error -2

Discuss with WPI FAE, they share one solution with me, patch link:https://patchwork.kernel.org/patch/6694971/

Do more once time test, another issue pop-up.

It is one serious and block issue for us, could you help us fix it ASAP? 

Thanks.

Hi Aaron,

As to  the above issue information, I try to comment out aic32x4_setup_regulators（）in aic32x4_i2c_probe（）,then the error log disappeared.

       //ret = aic32x4_setup_regulators(&i2c->dev, aic32x4);

       //if (ret) {

       //     dev_err(&i2c->dev, "Failed to setup regulators\n");

       //     return ret;

       //}

Unfortunatelly, there are still error information in kernel massge, except  “not registered” , does it mean codec registe success????

Next step, I try to run audio sample code and verify the codec basic function, but it failed. From the log, we can found some error information, like "set HW parameters"

/usrdata # ./example_audio play1 demo.wav

read wav hdr

get wav hdr offset

Ql_clt_set_mixer_value, device: SEC_AUX_PCM_RX Audio Mixer MultiMedia1, value: 1

Ql_clt_set_mixer_value, set mixer: SEC_AUX_PCM_RX Audio Mixer MultiMedia1 sucess

__ql_pcm_setParams, 401

cannot set hw params

__ql_pcm_open:params setting failed

Ql_AudPlayer_Open:Failed in __ql_pcm_open

Segmentation fault (core dumped)

/usrdata #

Double checked the kernel log，the issue caused by the mclk wrong value, till now, I don't know the root cause.

Above is my initial analysis, could you help me find the root cause?
