Hi Russell, I am currently working on implementing DMA Engine for omap serial driver. Came to know from santosh that you had suggested that certain modification need to be done in the tty core layer, which I am unaware of. Can you please explain what sort of changes need to be done? -- 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
