Our driver never sets those so we _should_ never get a WAKEUP_INT. Bits 8-10 are marked as RESERVED on the exynos5420 manual, so the current guess is that they're broken on that silicon but that sometimes the interrupt fires anyway. In any case, it is still a reasonable thing to clear this interrupt at wakeup if it has fired, even if we're on an exynos device without any problems. -Doug -- 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
