When only I/O wakeups can occur on those GPIO lines (when CORE/PER is in a low-power state), they are intrinsically debounced :-) So it should be fine. You are re-enabling the DEBOUNCENABLE bits in omap2_gpio_resume_after_idle() I assume? If so, that should be a good workaround for mainline too. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
