I've been told that omap's implementation is too different and I should stay out of the common code. Nice to see that that will be brought together as far as possible. > A similar check is added for the tx chanenl.

Sending XON/XOFF after TX completed would also be away. Pausing the transfer will lower the chance of an overrun. This requirement can't be fulfilled by OMAP-DMA, right? > Regards, Sebastian -- 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
