Im using phytec segin board in that by default tlv320 codec is present ,im disabling that codec and integrating wm8960 codec and i did the necessary changes in the dts files as shown below.But i could see that in " i2cdetect -y 0 " command i found at address "1a" its "UU" which means the wm8960 driver is probed.But why sound card is not detected
Is there any other place where i need to update.

Hello,
Could you please try to add the configuration to the I2C port in the device tree.
&i2c2 { clock_frequency = <100000>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; codec: wm8960@1a { compatible = "wlf,wm8960"; reg = <0x1a>; clocks = <&clks IMX6UL_CLK_SAI2>; clock-names = "mclk"; wlf,shared-lrclk; };
Furthermore, make sure that you have added correctly the driver to the kernel.
Unfortunately, the board that you are using is not an official NXP board. What we could help you is with the configuration that we have for our boards. I apologize for the inconvenience this could give you.
Best regards,
Diego.
