Subject: [PATCH v4 10/11] tty: 8250: Add support for Intashield IX cards

Add support for the IX-100, IX-200 and IX-400 serial cards.

Cc: stable@...r.kernel.org
Signed-off-by: Cameron Williams <cang1@...e.co.uk>
---
For stable: This patch is only applicable to 5.15 LTS and up, other LTS
kernels dont have the neccesary quirk options available (in patch 11) to
have these cards work correctly.

v3 - v4:
Add Cc: tag.

v2 - v3:
Re-submit patch series using git send-email to make threading work.

v1 - v2:
This is a resubmission series for the patch series below. That series
was lots of changes sent to lots of maintainers, this series is just for
the tty/serial/8250 subsystem.
