Hmm... I'm not seeing the firmware for this driver at the
linux-firmware tree:
	https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/log/

Nor I'm seeing any pull request for them. Did you send it?
I'll only merge the driver upstream after seeing such pull request.

Regards,
Mauro
