    Haji,

    The TPD12S521 is a protocol passive device, so there is no driver needed.

    Hi Chuck,

    Thanks for the input.

    We are using the i.MX8MP processor. As per the hardware connection:

    • DDC_CLK_IN is connected to I2C_CLK.
    • DDC_DAT_IN is connected to I2C_SDA.

    Can you please provide the TPD12S521 chip Linux kernel device tree configurations?

    Regards,
    Haji

    Haji,

    The TPD12S521 is just a level shifter and ESD protection device.  It is totally transparent to any driver.  If you have the i.MX8MP driver, then you have everything that you need.
