Make dw8250_set_termios() as the default set_termios callback for 8250
dw uart, correct me
if I am wrong.

Then add ACPI support for uart on Hisilicon Hip05 soc, be careful that
it is not 16500
compatible.

You mean it has Busy Functionality implemented?

After check it again with designer, yes.

Is there any public specification to look at?

I think Xin liang is in a better position to answer this question.

 Note, the build(no ACPI) depends on
https://patchwork.kernel.org/patch/9141207/,
which was already accepted in net-next.

Meanwhile, set dw8250_serial_out32 to keep consistent between
serial_out
and serial_in in ACPI.
