TLV320AIC3263: Linux kernel v5.4 driver

Hi Yusuf,

I'm looping our software team to assist, but the 3x family is different than the 326x family. I don't expect these drivers to be compatible. As to if something is available, wait for our software team to answer.

Best regards,

Jeff

Hi Yusuf

Where do you find the driver code for tlv320aic3263? I found the linking is invalid in ti.com.

Tell me the link, and we can help to driver to support the v5.4.

Link in ti.com said "Invalid branch: tlv320aic3268_44_kernel". In that page, I click to file name and its opened (in master branch i guess). 

tlv320aic326x.c = git.ti.com/.../tlv320aic326x.c
tlv320aic326x.h = https://git.ti.com/cgit/ti-analog-linux-kernel/dmurphy-analog/tree/sound/soc/codecs/tlv320aic326x.h?id=07adbd28685347b6dad5c6dd651f8b2bfa0ddaf8

0572.current.7z

There is an error in tlv320aic326x.c. snd_soc_component_read function needs 3 parameter but have 2 parameter.  I think we should change function calls like this, right?

hpl_hpr = snd_soc_component_read(codec, AIC3262_POWER_CONF); -> snd_soc_component_read(codec, AIC3262_POWER_CONF,&hpl_hpr);

Go ahead. We have no 5.4, but  5.10. So this code compile in the 5.10

In DTS, I tried "ti,aic3268" and "ti,aic3262" (according to tlv320aic3xxx-i2c.c, I have only these two compatible options). Driver said "Device is not a TLV320AIC3262" for both options.  In tlv320aic3xxx-core.c file, readed device ID should be 3 but in my case device id registers response is 6. I found aic3xxx_type enum in tlv320aic3xx-core.h but aic3263 is not defined here and non of thems id is 6. Am i doing something wrong?

Let me check internally

Hi

Do you have any updates ?

Hi Baves

We have no driver code directly support aic3263, but we can reuse aic3262 driver code

The main difference with AIC3262 is enhanced miniDSP (clocking definitely, memory maybe) and 4 CICs which enabled four digital mics.

Good luck
