Well, it depends what aspect you find complicated. It is pretty 
straightforward device that just needs a driver to work.

I do. The fact that you see a subdirectory mmc1:0001:2 in 
/sys/bus/sdio/drivers/brcmfmac_sdio means that the driver was probed for 
this device. Now would be a good time to share your (friends') kernel 
log, but my guess is you are either missing firmware or nvram data or 
both for this device.

And could you try to answer inline instead of top-posting.
