Thanks for your time.  Sorry I didn't know there is a mixer-test in
the kernel tool
folder, I misunderstood mixer-test was a tool designed by Toradex. I
found the tool
now.

I am running the test, and trying to fix the issue caused by this
patch set.  but I also
find some issues for other devices in fsl, which I will fix later.

Thank you again for this useful tool.

Best regards
