[PATCH v3 0/7] Brainboxes serial cards additions/fixes

[PATCH v3 0/7] Brainboxes serial cards additions/fixes

[Cameron Williams]

This series adds and fixes the Brainboxes PCI/e range of serial cards,
adding any missing production card IDs and fixing any bugs, mainly with
the Oxford Semiconductor based PX cards.

Change from v2 [1][2][3][4][5][6][7]:
- No code changes
- Amend patch 1 and 5 commit comment to better clarify what has been
changed and why
- Send using git send-email instead of Mutt so (hopefully) the
threading works OK

Change from v1 [1][2][3][4]:
- Split the patch into multiple commits for one subsystem/maintainer
rather than a large series for multiple subsystems.

[PATCH v3 1/7] tty: 8250: Fix IS-200 PCI ID comment

[Cameron Williams]

Fix the PCI comment for the IS-200 card. The PCI ID for the IS-200
is 0x0d80, and the definition used (PCI_DEVICE_ID_INTASHIELD_IS200)
is indeed 0x0d80, clarify that by fixing the comment as its
neighbouring cards are all at 0x0020 offsets.

[PATCH v3 2/7] tty: 8250: Add support for additional Brainboxes UC cards

[Cameron Williams]

Add support for additional revisions/IDs of the Brainboxes UC
range of serial cards.

Add: Additional UC-235/UC-246, UC-302, UC-313, UC-346, UC-357 card IDs
Add: UC-253/UC-734 , UC-607, UC-836 cards 
Fix: UC-431 variant note removed as it is a 3-port card, and there is
no generic 3-port configuration available.
Fix: UC-257 moved to parport_serial as it is a serial/LPT card.

[PATCH v3 7/7] tty: 8250: Add Brainboxes Oxford Semiconductor-based quirks

[Cameron Williams]

Some of the later revisions of the Brainboxes PX cards are based
on the Oxford Semiconductor chipset. Due to the chip's unique setup
these cards need to be initialised.
Previously these were tested against a reference card with the same broken
baudrate on another PC, cancelling out the effect. With this patch they
work and can transfer/receive find against an FTDI-based device.

Add all of the cards which require this setup to the quirks table.
Thanks to Maciej W. Rozycki for clarification on this chip.

The real question is why to maintain a comment here at all? I suggest 
dropping them both instead.

So can it be fixed instead of removed?

So this patch deserves a Fixes tag and should go to stable as well?

Anyway, could you split this into fixes and additions (ie. 2 patches)?

I try to avoid touching other people's code unless it's wrong as is the
case here. I could remove them both but since they both (IS-200 and IS-400)
refer to the definition in pci_ids.h, and the rest of the cards use the raw
hex IDs instead, its more consistent to have them all showing the card ID in
one way or another, IMHO.

By fixed, do you mean implement a generic 3-port configuration?

If you mean fixed as in change the wording a little bit and add a Fixes:
tag, then I can do that too.

Thanks Jiri. I'll take your notes on board and see if anyone else has input
too before v4-ing this series.
