Huh, you mangled even e-mails:

5.1.0 - Unknown address error 550-'5.1.1 <ilpo.jarvinnen@xxxxxxxxxxxxxxx>: Recipient address rejected: User unknown in virtual mailbox table'

<linux-kernel@xxxxxxxxxxxxxx>: Host or domain name not found. Name service
error for name=vger.kernel.rg type=AAAA: Host not found

This patch is proposing a custom configuration for Synopsys DesignWare
serial to be used by products with associated compatible string in the
device tree.

The PORT_DWAPB config will be used instead of the default PORT_16550A
which does not include the UART_FCR_CLEAR_RCVR and UART_FCR_CLEAR_XMIT
bits for the FIFO configuration register. Having those flags is necessary
to clear FIFO when the serial port is reconfigured with do_set_termios.

How was this tested? I assume it does not even compile.
