I was worried that the first patch would add too much overhead, and cause the hardware to overrun - as the ARM version of these primecells does not have the capability to stop the clock when the FIFO fills up, any increase in IRQ latency to read the FIFO will result in an overrun. So this is good news. I've applied the first three patches in this series, but we do need to sort out the card detect situation properly before continuing. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
