Thanks - OK.

I think that the vendor name is coming from a DMI fallback:


Whether the model name is from DMI or from the DTS file's 'model'
field is less clear to me:


I'll try to rebuild the kernel module and test some changes 'soon'
(within the next few days, most likely).

Also, to clarify an error/thinko in my previous message: the style of
filename we agreed to map to, and that both linux-firmware.git and the
RPi operating system distro[1] use, is
"brcmfmac43456-sdio.raspberrypi,400.txt" (not the short-format
"brcmfmac43455-sdio.txt" that I mentioned).  We should include
specificity for vendor and model in the filename, all lowercased, and
without spaces.

The RPi 400 model firmware files are not yet represented in
linux-firmware.git, although they do appear in the RPi operating
system distro.
