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
