Hello, I am using imx6ul, the kernel is linux4.14.78,
I used the i2s external audio chip, but the audio clock is wrong and I can't generate the clock I want. I checked the imx6ul chip manual and found
The register configuration is 10 for PLL4 as the parent clock. But I read it out is 00.
My device tree configures the PLL4 bit parent clock
I should do it exclusively？
