I believe that to merge a driver (non staging) that depends on a firmware (I'll
let Hans and others confirm), you need to submit this firmware, along with a
non-interactive licence to be included in the linux-firmware project.

NXP notably have an SDMA firmware in there, with a licence file. Perhaps these
developers can assist in this regard. Often that takes time due to legal
requirement of moving from an interactive EULA to a licence file.

In later version, it would be nice to explain in the cover later the status of
firmware distribution, and how to obtain the correct version of (specially if
not yet in linux-firmware).

Thanks for sending me the firmwares, I will see if I can do more tests.
