Hi,
I'm working with a driver for an SDIO Wireless LAN card and just tried
it out on an i.MX35 based development board (Phytec PCM-043). My
impression is that the sdhci-esdhc-imx driver doesn't support SDIO
interrupts, is that correct?
Regards,
PH

I think we didn't test this on the PCM043 so far, so it probably won't
work without further activities.

Just having a quick look at the code and a few printouts from sdhci.c
indicates that SDIO IRQs are enabled but in the end the eSDHC controller
doesn't report any IRQs. On the other hand, the IRQ handling for SDIO
IRQs in sdhci.c doesn't follow the steps described in the i.MX35
Reference Manual (but that doesn't explain why there is not one single
SDIO IRQ reported).

I commit a patch to fix this issue. Did you update your code?

Sorry for my stupid question but where did you commit that patch?

Thanks! Merged relevant parts with 2.6.93.4 and the mach-mx3 platform
and now it seems like SDIO interrupts are working fine. Sweet :)
