There appear to be least seven SDIO card drivers in 2.6.34-rc7. At least
one of these is for a TI chip - the wl1251. I think some of the

That is correct, a Wi2Wi wifi module is connected via mmc2 on the
Overo Air and Fire products.
A dumb question. Is this Wi2Wi wifi module available as a standard SDIO card
which can be plugged into a SD card cage? Or is it

A little bit of rearranging the David's changes to the irq handler gets the
MMC/SD cards to work fine again. Changes are shown in the attached patch for
now and it should not hurt the CIRQ handling as well.
This breaks detecting card interrupts unless a command is in

My question was more related to the idle path. In a scenario where
you start using the SDIO functionality and after some time you leave
the SDIO card idle, does the FCLK still remain enabled? Or do you see
that sdio_irq_thread exits and disables the FCLK?
What do you mean

If I look in the mainline kernel today there is only one SDIO card driver
sdio_uart.c. And at least I don't see a way I can test any of these
features myself.
There are many other SDIO drivers in the kernel today:
