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. 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.

We can safely use dw8250_set_termios() as the default set_termios
callback instead of serial8250_do_set_termios(), so do it.

Add ACPI identifier for UART on Hisilicon Hip05 soc, be careful
that it is not 16550 compatibal.
Meanwhile, set dw8250_serial_out32 to keep consistent between serial_out
and serial_in in ACPI.

You mean it has Busy Functionality implemented?
Is there any public specification to look at?

Sorry, our SoC manual is not that public. But we confirm with SoC guys
that 8250dw has 16550 compatible and non 16550 compatible version.
Ours is non 16550 compatible version. And we can see the IIR register
has busy interrupt bit:
"0x7: busy interrupt. When UART is busy (USR[0]=1) in receiving
and transmitting data and the processor operates the LCR register,
this interrupt will be generated."
