Hello all,

I wonder how to set the CPU frequency manually. I looked in the kernel config (buildroot) and see that the Rockchip cpufreq driver is enabled but looking in the code it seems as if that driver doesn't support RK3506B. Is there any way to set the CPU frequency from user space?

The PCM5102A works fine. Here is a quote from the datasheet:

Integrated High-Performance Audio PLL with BCK
Reference to Generate SCK Internally

Just pull SCK low and it'll output audio just fine.
