SDIO in-band interrupt is level sensitive according to SDIO standard.
When the register interrupt handler gets called by SDIO stack it is
running in non interrupt context and expected to clear the interrupt
from the dongle. Therefore in-band and out-of-band interrupt need to
be handled differently.

For reference, I took next-20120914, applied this patch series, applied
a few patches from Wei Ni to set up the SDIO HW on Tegra correctly, and
tested. The last time I tried this without any patches to the brcmfmac,
this test caused some system instability issues. This time around, I
observed no instability. I tested WPA PSK, ping (or flood ping) plus
playing audio through ALSA.
Is this series likely to make 3.7?
Thanks, Stephen
Good to hear. I suspect we are close to the 3.7 merge window, but we do
hope this will make it mainly for the tegra sdio issue that Wei Ni
raised. In general the series should resolve issues when used on
sdhci/mmc framework with in-band interrupt.
Do you still need the patches from Wei Ni and are they SDIO or brcmfmac
related?
