Your changes also don't work because serial uart drivers are not =

many do not do so and the performance hit would be too high. =20

The SoC I have, is using it.

The Linux kernel does generalised implementations. Yes it may work on
your board but it doesn't work for everything.

It needs to work only on boards with a SoC UART. Not with a tty over
USB or something else. This is the generalisation I see. Any SoC with
uart_port driver support (and as far as I see many are).

It's the difference
between doing it properly and hacking your board to work.

Agreed. But solving problems nobody really has is overengineering.

Especially if the generalised implementation that is being discussed
(tty_port) does not even solve the problem. Or only in a very clumsy
and difficult way. In such a case a generalisation seems to be the
wrong approach to me.

And we should start to accept that we mix up different requirements
and try a single solution for almost everyone we can imagine (which
isn't bad initially, but can prohibit to find a solution at all) except =
the
real use case that is on the table. That is why I always come back
to the practical problem to implement my driver and want to know
how it can be done.
