As Jonas mentioned the general principle of device tree is to be
agnostic with regards to OS and/or driver as you undoubtedly know. His
proposal seems like a usable solution for your problem while complying
to the device tree principle. So instead of overriding the default
brcmfmac should modify it when dt specifies the "module" property, ie:
no "module" in DT: nvram filename = brcm/brcmfmac43362-sdio.txt
"module=ap6210" in DT: nvram filename = brcm/brcmfmac43362-ap6210.txt
Just out of curiosity, what does "ap6210" exactly mean? I get that 43362
is the chip id, but not ap6210. Is it just an arbitrary name?
It is more or less an arbitrary name, typically these sdio wifi chips
are used as a pre-assembled module (a tiny pcb) with some things like
the necessary crystal / resonator and various capacitors and resistors
on there. The brcm based sdio wifi modules typically come with a metal
shield cap which has a module type stamped on it, e.g. ap6210,
ap6476, toc9002.

Hans
