And there is no reply from NXP for 3 months. You are right that nobody knows what is in firmware binary, but working binary is at least usable than non-working binary. So I would really suggest to start reverting non-working firmware files if NXP does not respond in few days. G=E9rald, what is your opinion?

Josh, as G=E9rald wrote, current binary in linux-firmware repository is
unusable. And there is no reply from NXP for 3 months.

You are right that nobody knows what is in firmware binary, but working
binary is at least usable than non-working binary.

So I would really suggest to start reverting non-working firmware files
if NXP does not respond in few days.

G=E9rald, what is your opinion? Do you see other way how to make mainline linux driver work (again)?
