How-to use the sdio driver?

[Lars Holowko]

Hi everyone,

I am trying to get to run the libertas SDIO driver to work on an Atmel
AT91SAM9G20-EK eval board (linux-2.6.30.1).

After an insmod libertas_sdio.ko I see this on the console

libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman

but obviously if_sdio_probe never gets called (I added a printk there).

Is there anything else I have to do? I looked at
arch/arm/mach-at91/board-sam9g20ek.c and it looked like the default
configuration for the GPIO's look ok (I try to use the MCDB* GPIOS).

I think it would already help me if someone could outline for any
platform what needs to be done in general.

I would also appreciate if some could share an example how one can
activate the GSPI version (the docu for this on the website is a little
bit brief) - I want to compare the throughput that can be achieved with
both versions.

Thanks in advance,

Lars
