Machine driver for TLV320AIC3100 codec

Hi all,

I able to find the problem, it is because probe function of tlv320aic3x.c is not calling.
so i am not able register it and also there is no board specific file under arch/arm/ to assign i2c probe manually.
like

vim ./arch/arm/mach-s3c64xx/mach-

static struct i2c_board_info mxc_i2c0_board_info[] __initdata = {
    {
            I2C_BOARD_INFO("sgtl5000", 0x14),
    },
};

Hi, Punith,

I'm glad you found the area causing the problem.

As I mentioned before, we are unfortunately not able to provide support debugging these types of issues.

Sometimes other members of the community chime in with their experience. Guys?

 Hi Guys.

Here i did same thing but directly in codec driver ,

vim sound/soc/codec/tlv320aic3x.c

/* added by punith */
static struct i2c_board_info __initdata aic3x_i2c_board_info[] = {
        {
                .type = "tlv320aic3x",
                .addr = 0x18,
                //.platform_data = &axp_pdata,
                //.irq = pmu_irq_id,
        },
};

static int __init aic3x_modinit(void)
{
        int ret = 0;
        ret = i2c_add_driver(&aic3x_i2c_driver);
        printk("%s puneet\n",__func__);

        /* addedd by punith*/
        i2c_register_board_info(2, aic3x_i2c_board_info,
                        ARRAY_SIZE(aic3x_i2c_board_info));

        if (ret != 0) {
                printk(KERN_ERR "Failed to register TLV320AIC3x I2C driver: %d\n",
                       ret);
        }
        return ret;
}

But not yet able to probe the codec.
My codec in bus /dev/i2c-2 and address is 0x18. so i passed codec_name=tlv320aic3x-codec.2-0018

Do you any idea, kindly tell me

Hi all,

Here i not getting how to create 4 regulators IOVDD,DVDD,AVDD,DRVDD.

For IOVDD=AVDD=3.3V and DVDD=1.8V but what will be voltage for DRVDD=? for chip set TLV320AIC3100.

Here will be link for my schematics of A20 board , KIndly tell how can pass get these 4 regulators.

Kindly tell me.

Hi All,

Once i did some changes in my machine driver , i am able to play audio in my board.

This one i can see in my console and by using log but not able to hear form HPLOUT and HPROUT pin.

Once i probe while playing audio ,

mclk=11MHZ

blck=wclk=2.8MHZ

and able to get signals also in dout pin and din pin  which is of frequency 2.8MHZ.

Is it because of not proper  mapping of  audio route in machine driver or something else.

In my board we are taking only HPLOUT and HPROUT form TI codec and remaining pins are not connected .

Here  i am attaching log once i play audio through codec,

Kindly tell me why i am not getting any audio through HPR and HPL out pins.

Hi TI guys,

For TLV320AIC3100 chip set which driver i need to use?.

Is it ok the commenting all regulator function in codec driver since i have all voltages in Hardware(for olny testing)?.

Regards

Punith

Hi All,

Here my actual register output. I think if go though this , it will be easy to point out the problem.
Here i am attaching my all register programmed value and machine driver code and schematic of codec.

Once i play mp3 file through codec sound card i am getting 1.46V on HPL and HPR line and going to 0v once i stop audio but not getting any audio signals.

The value of MCLK=11MHZ BLCK=5.8MHZ and WCLK=58KHZ and getting signals in DIN pin also.

In our case  all clocks are coming from processor we are not any crystal oscillator to generate the clock.

Your help will be greatly appreciable.

Regards

Punith

Here will be machine driver code

Hi All,

Finally i am able to do some improvement in my codec , now i am able to generate beep (exactly 2khz by programming beep registers) .but still i am not able to get any audio in HPL and HPR line.

In my case codec is slave and cpu is master. here is my clock configuration

MCLK=5.6448MHZ

BCLK=1.411MHZ(for 16 bit ws)

WCLK=44.1KHZ.

I tested the data in from cpu to codec by playing the wav file which contains only 'A5' data. feels DataIN is ok.

here i am attaching my logic analyser output and register dump of codec chip set.

If anyone have idea  kindly suggest me.

Regards

Punith
