Hi team,

Good day.

Do we have the device tree structure for the TAS2505? Our customer is using Yocto Zeus BSP and they're requesting complete information on TAS2505 Linux driver integration along with device tree binding.

Regards,
Carlo

    Hi Carlo,

    I'm adding feedback below:

    The MCLK and samplerate is hardcoded in tas2505 code.

    MCLK is 12288000. But in tas2505_set_dai_sysclk, system pass the values of freq is not 12288000. So In tas2505_setup_pll, the return value is wrong.

    Hello Ivan,

    Thank you for the information. Do the customer need to make changes in the driver source code? I did not find any information regarding the device tree, could you please help with that?

    Regards,
    Carlo

    Carlo,

    Correct, my understanding is that if customer is using clocks not included in tas2505 code, they need to input those manually into the code.

    This driver code for tas2505 was not developed by TI, so unfortunately we don't have any reference material other than the code itself.
