Still, this is something you have not tested on the u200 reference
design. I believe this was already discussed in the past.

The u200 is far more complex when it comes to audio and certainly would
not work on this no-name android device. These device are heavily
"inspired" by the reference, but trimmed down in many aspect including
audio capabilities - NOT copied.

People abusing the u200 or p200 DT does make the patchset valid
