Thanks for the patch. As you may have inferred from my reply to your MFD series, this won't be needed for a while still however. Also note that some people already use asynchronous FIFO mode using this driver (also mentioned in the datasheets as an option) so only binding in UART mode would be too restrictive. Thanks, Johan
