The problem is that there is a SDIO card which has up to 7 functions, but it itself has some characteristics that are available at function 0. If we add, say, sdio0 device and store this information there, we end up with the hierarchy suggested by Ben Gray a year ago. The SD-specific functions like CSD/CSR operations are also in the mmc.c and considered to be the bus code... Or am I missing something obvious here? > I would try to look for SDIO Bluetooth card.

The SDIO card found in the Dreamplug has three functions, one of them is Bluetooth. Will try to find some docs / Linux code for that... -- Regards, Ilya Bakulin
