hello
my board is imx8mm android10 kernle5.4.47，I added WM8962 in the imx8mm-evk.dts。
308 sound-wm8962 {
309 compatible = "fsl,imx6q-sabresd-wm8962",
310 "fsl,imx-audio-wm8962";
311 model = "wm8962-audio";

WM8962 was found in the boot log。

But WM8962 has no sound,It doesn't seem to have been called。
Linux 4.14.98 wm8962 is ok。
How do I change Android10？
