One technical correction on this section -- rather, the CORE* clockdomains will not be allowed to go idle when the PM runtime autosuspend timeout is -1. And that is what causes the character loss. The rest of the E-mail stands. The question of whether the UART should be allowed to enter idle is a different one, since the current driver is not properly working in this regard, which is why we're not getting RX timeout events, etc. We should be able to have the proper RX timeout behavior, and therefore use normal FIFO thresholds, by fixing some of the bugs in the existing driver. - 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
