> On the A733, dw8250_set_termios() stops the UART clock around
> clk_set_rate() on every termios change that reaches the driver. If TX is
> active at that moment, the character being shifted out is corrupted.
>
> No baud rate change is required to trigger the problem. Toggling only
> CLOCAL or CSTOPB 300 times during continuous console output corrupted
> bytes in every run without the quirk and in none with it.
>
> Use the existing SKIP_SET_RATE quirk, as the JH7100 and SG2044 UARTs do.
