This driver supports the Siemens Gigaset SX205/255 family of
ISDN DECT bases, including the predecessors Gigaset 3070/3075
and 4170/4175 and their T-Com versions Sinus 45isdn and Sinus
721X.
If you have one of these devices, say M here and for at least
one of the connection specific parts that follow.
This will build a module called "gigaset".
Note: If you build your ISDN subsystem (ISDN_CAPI or ISDN_I4L)
as a module, you have to build this driver as a module too,
otherwise the Gigaset device won't show up as an ISDN device.
