Somebody in the thread at some point said:
| This comparably high interrupt rate is expected behaviour, as far as
| SDIO is concerned. What happens is that the SDIO stack polls the
| device periodically for pending interrupts, which involves sending a
| command over the bus each time, which in turn produces a completion
| interrupt on the host side.
|
| The stack does this seemingly foolish thing because the S3C MMC
| driver does not support handling SDIO interrupt as real interrupts.
Wow so while SDIO-based WLAN is up on 2442, there's 100 wakes a second.
Does the 2442 peripheral device support recognition of SDIO interrupt
signalling action? Where does that problem begin?
