From: Crescent CY Hsieh
Date: Wed Oct 18 2023 - 05:20:42 EST


These patch series do some changes to MOXA PCIe boards in 8250_pci.c,
including:

- Modify MOXA enum name within 8250_pci.c
- Cleanup MOXA configurations within 8250_pci.c
- Relocate macros within 8250_pci.c
- Add support for MOXA Mini PCIe boards
- Fix MOXA RS422/RS485 boards not function by default
- Add support for MOXA PCIe boards to switch between different serial
interfaces

Each patch depends on previous one.

Changes in v3:
- Add reviewer tag in first 4 patches.
- [PATCH v3 2/6]:
- Make commit message clearer.
- [PATCH v3 5/6]:
- Delete pci_moxa_match_x3xx() function.
- Introduce pci_moxa_match_second_digit() function.
- [PATCH v3 6/6]:
- Delete pci_moxa_match_x1xx() function.
- Replace pci_moxa_match_x1xx() and pci_moxa_match_x3xx() with
pci_moxa_match_second_digit().
- Add comment at pci_moxa_rs485_config().

interface.

Changes in v2:

- Introduce functions for checking device ID pattern.
- Replace magic constant with BIT().
- Sort macros into pre-existing macro list.
- Rewrite set_interface condition architecture.
- Utilize unused flag to represent RS422 interface instead of adding a
