Subject: [PATCH v2] usb: serial: ti_usb_3410_5052: add MOXA UPORT 11x0 support
Add support for :
- UPort 1110 : 1 port RS-232 USB to Serial Hub.
- UPort 1130 : 1 port RS-422/485 USB to Serial Hub.
- UPort 1130I : 1 port RS-422/485 USB to Serial Hub with Isolation.
- UPort 1150 : 1 port RS-232/422/485 USB to Serial Hub.
- UPort 1150I : 1 port RS-232/422/485 USB to Serial Hub with Isolation.
These devices are based on TI 3410 chip.

Hi,
Here is the second version of the patch.
Thank you,
Mathieu
Changelog:
v2:
* Add a rs485_only flag to device structure.
* Try to load moxa firmware without fallback.
