From: Parker Newman <pnewman@connecttech.com>

Hello,
These patches add proper support for most of Connect Tech's (CTI) Exar
based serial cards. Previously, only a subset of CTI's cards would work
with the Exar driver while the rest required the CTI out-of-tree driver.
These patches are intended to phase out the out-of-tree driver.

I am new to the mailing lists and contributing to the kernel so please
let me know if I have made any mistakes or if you have any feedback.

Changes in v2:
- Put missing PCI IDs in 8250_exar.c instead of pci_ids.h
- Split large patch into smaller ones

Changes in v3:
- Refactored patches to be easier to follow (based on feedback of v2)
- Patch specific changes listed in corresponding patch

Changes in v4:
- Rebased to tty-testing branch
- Removed v3 patch 8/8, "bug" didn't happen in current driver
- Patch specific changes listed in corresponding patch

Thank you,

Parker Newman (7):
  serial: exar: remove old Connect Tech setup
  serial: exar: added a exar_get_nr_ports function
  serial: exar: add optional board_init function
  serial: exar: moved generic_rs485 further up in 8250_exar.c
  serial: exar: add CTI cards to exar_get_nr_ports
  serial: exar: add CTI specific setup code
  serial: exar: fix checkpach warnings

Nice, compared to your first version, this is less code overall in this
file:
   1 file changed, 1019 insertions(+), 70 deletions(-)

so the review process helped!

All now applied to my tree, thanks for the revisions.  And a follow-on
patch to fix up the kbuild warning would be appreciated.

thanks,

Yes thanks again for your patience. I learned a lot about the process :).

I will follow up with a mini-series now to fix the kbuild warnings and a
couple minor things mentioned by Ilpo.

Thanks,
