NAK, for what it is worth..
This is a plain old shitty situation, that everyone that mistakenly
chooses a BRCM based chipset in a design faces, then learns to NEVER
touch that chipset again..
These nodes have been posted before for mainline inclusion but always
get killed off:

The TI AM57xx SDIO needs these flags for the brcmfmac driver to actually work.
I don't see the brcmfmac developers actually fixing it, as "out of
tree" work for brcmfmac is 100+ patches long:
