Part Number: TLV320ADC5140

Hi Team,

We are trying to integrate tlv320adc5140 to renesas based rzg2h board and we are using kernel-5.10.158.

We followed instruction given in the file Guideline\ for\ PCMDEVICE\ driver\ on\ Linux.pdf.

we followed below step:

1) copy the src into sound/soc/codecs and named as pcmdevice

2) Modified the Kconfig file to incude pcmdevice

3)Made the changes in Makefile

While Compilling the source we are getting the below error:

Looks like it is not compilling with kernel-5.10.158 , please suggest workarounf for this error:

IS there a 5.10.158 version source available, please guide us.

Thanks and regards,

Here is the example to how to fix it.

tasdevice-core-i2c.c « src - tas2781-linux-drivers/tas2781-linux-driver - Unnamed repository; edit this file 'description' to name the repository.

Hi Shenghao Ding,

We don't have tasdevice-core-i2c.c in the source folder

My source folder is:

adc5120-irq.c Makefile pcm6240-irq.c pcm6260-reg.h pcmd31x0-irq.c pcmdevice.h pcmdevice-ops.c pcmdevice-regbin.h taa5412-irq.c adc5120-reg.h pcm186x-irq.c pcm6240-reg.h pcm9211-irq.c pcmd31x0-reg.h pcmdevice-node.c pcmdevice-ops.h pcmdevice-rw.c taa5412-reg.h Kconfig pcm186x-reg.h pcm6260-irq.c pcm9211-reg.h pcmdevice-core.c pcmdevice-node.h pcmdevice-regbin.c pcmdevice-rw.h.

Am I using the correct source or not please guide us.

Thanks and regards,

Nagaraja

there's an example on how to modify probe and remove function to adapt kernel-5.10.158 in tasdevice-core-i2c.c

Hi Shenghao Ding,

Thanks for the reply , now we are able to compile the driver,

My dts entries is as below: IT was working with default device driver tlv320adcx140.c but I was not able set the volume because it was very low, so

I integrated pcmdevice driver as per your suggestion.

                              };
                   };

};
};

With Above setting in my dtsi I was able to record an audio with command below

arecord -D plughw:0,0 -r44100 -f S16_LE -c 1 -d 5 reccord704.wav.

As I posted in the forum audio volume was very low and I was not able to increase it.

Is there any changes required in dtsi entries above for pcmdevice driver to work. Now we are not able to record after the integration of pcmdevice driver.. Please guide us how do I go about it. Is there any document available with details and steps.

Thanks and regards,

Nagaraja

Sample code for volume kcontrol is in the following patches, kindly focus on adc5120_analog_gain_ctl and adc5120_digi_gain_ctl in v9-0001, study how they are referenced.

Hi Shenghao Ding,

As I mailed earlier we are able to integrate pcmdevice-linux-driver from Ti as guided by you. Now after loading the firmware file pcm5140-1dev-gen.bin.

We are getting below messages:

Kindly use scope to measure the blk and WS clk and upload the waveform here. One more thing, kindly also dump the registers.

Hi Shenghao Ding,

We are not getting blk and WS clk

Hi Guy

clk is very important for acd5140. because adc5140 is a slave device in your project according to the dts setting you offered, which depend on the bck and ws clks from your platform. Without both of the clk, adc5140 can't work.

Hi Shenghao Ding,

The dts setting above is working with kernel-5.10.158 when I use tlv320adcx140.c

which comes with main stream kernel:( Only problem i had was volume or very low in this case so i migrated to pcmdevice package as per your advice)

So I have few thing to know:

1) How should I configure adc5140 : is it suppose to be slave OR Master

2) If I integrate pcmdevice packages from TI, do I need to disable tlv320adcx140 driver in the kernel menuconfig or we still need it.

3) What should be the dts entries: (please send me any working dts for reference)

compatible = "ti,tlv320adc5140";

or
compatible = "ti,pcm5140";

4) what is the advantage of pcmdevice packages over main stream kernel driver

tlv320adcx140.c

Thanks and regards

Nagaraja

Hi Guy

The same arch as pcmdevice has been upstream into Linux-next, it will be merged into mainline soon. pcm6240.c « codecs « soc « sound - kernel/git/next/linux-next.git - The linux-next integration testing tree

The code can support one piece, two pieces, even multiple pieces in one driver code, and all registers has been set into the bin file.

You won't recompile the code because of a single code change.

the same code can support different chips.

In your old dts setting, you set5140 as slave.

Now, which code do you decide to use?
