NXP people: Sharvari, Rakesh, Cathy, Zheng: could you please look at
this issue? It is really serous!

Josh, as Gérald 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.
Gérald, what is your opinion? Do you see other way how to make mainline
linux driver work (again)?
