From: Sheng-Yuan Huang <syhuang3@nuvoton.com>

Hi all,

This patch adds a new driver for Nuvoton USB-to-serial adapters
in drivers/usb/serial.

The driver supports multiple virtual serial ports over a single
USB interface. It configures the device using vendor-specific
control messages, and handles data transmission via bulk endpoints.
Port status is reported either through an interrupt-in or a bulk-in
endpoint, depending on the hardware configuration.

Any feedback or suggestions would be greatly appreciated.

Best regards,  
Sheng-Yuan Huang
