This is NOT the same company as Cortina Systems and is NOT Realtek.  It’s is it’s own entity and does not have the right to use the Cortina Systems name with is owned by a different company.

MAINTAINERS modification was made in the initial version 1.  We made no changes to it since then,
thus not sure what we could at to  Changelog which would add value or clarity for others
from the v1.

You are also adding a MAINTAINERS entry here, which is not listed in the
changelog text, so I couldn't take it anyway :(

Add the maintainers entry in the first patch, with the driver please.

The change to MAINTAINERS here add a new file into the DT documentation.
Should it not be grouped into the dt-binding portion and reviewed by the DT time for which this patch
is CC’ed to? Why would moving the DT documentation file that is introduced be into the first patch, which is the
serial driver itself be the correct approach?

The binding doesn't actually need a MAINTAINERS entry (though having
one is fine). get_maintainers.pl will also pull emails from the
binding schema.

Hi Rob,
It sounds like you are find with patch 2/3 from a DT point of view.  Could we review the rest from the DT point of view
to get either feedback for changes or ACK these, so we can unblock this series?

Can't say I've seen it as I only see replies in my mail. Did this
originally go to the DT list? If not, it's never in my queue[1].

[1] https://patchwork.ozlabs.org/project/devicetree-bindings/list/

None of the patches in this series ended up on a mailing list or on
lore, so no one could comment on them, except for people CCed directly.

The driver has been accepted in tty-next, commit b61c8bf4694b5115
("tty: serial: Add UART driver for Cortina-Access platform").  From a
quick glance, it could have used some review.

The driver is using the compatible value "cortina-access,serial", so I
guess the binding patch added "cortina-access" to vendor-prefixes.yaml.
According to https://www.cortina-access.com/news-and-events, this is
the same company as Cortina Systems, which already has the "cortina"
vendor prefix.  In 2015, it was acquired by Realtek, so perhaps it
should use the "realtek" prefix instead for new development?

The SERIAL_CORTINA_ACCESS symbol doesn't depend on anything, so
it will show up on everyone's oldconfig radar soon, regardless of
building a kernel for a Cortina Access system or not.
I wanted to change it to something like:

    config SERIAL_CORTINA_ACCESS
           tristate "Cortina-Access serial port support"
   +       depends on FIXME || COMPILE_TEST
           select SERIAL_CORE
           help
             This driver is for Cortina-Access SoC's UART. If you
have a machine
             based on the Cortina-Access SoC and wish to use the serial port,
             say 'Y' here. Otherwise, say 'N'.

but given there is no evidence of patches to add support for the
CAXXXX line of SoCs, there's no symbol to depend on...

Gr{oetje,eeting}s,
