Well that's good news that it exists on 36xx+ at least. But please make a few changes. This shouldn't set this bit on UARTs that don't support it. It should only be set if a hwmod dev_attr flag was set to indicate the presence of this feature. Using a flag is also important since it will allow us to disable the workaround that we'll need for earlier OMAPs. Also, I assume that this does not fix the RX sluggishness due to the missing RX timeout wakeup? Also, this assignment should be using symbolic macros rather than raw bits. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
