Bluetooth HCI UART (PC Card) driver.
This driver provides support for Bluetooth PCMCIA devices with
an UART interface:
Xircom CreditCard Bluetooth Adapter
Xircom RealPort2 Bluetooth Adapter
Sphinx PICO Card
H-Soft blue+Card
Cyber-blue Compact Flash Card
Say Y here to compile support for HCI UART devices into the
kernel or say M to compile it as module (btuart_cs).
