It would be funny if the TRM was wrong and the CIRQ bit is really
cleared by writing 1 to it. I'll try that.

Do you have any idea about MMCHS_HCTL.IBG?
Not off the top of my head.
I was working with someone who hit issues so I did a quick spec read and came

It is not perfect yet, I am still polling in sdio_irq.c because
sometimes the card irq does get dropped. I suspect that is why the
davinci driver had extra checks and calls in various places.
Maybe.

Thanks for the update. After looking more closely at your patch I
