Joe Millenbach 4f73bc4dd3 tty: Added a CONFIG_TTY option to allow removal of TTY
The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.

The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer.  Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.

bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY.  The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

help
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.

help
Build the Gigaset driver as a CAPI 2.0 driver interfacing with
the Kernel CAPI subsystem. To use it with the old ISDN4Linux
subsystem you'll have to enable the capidrv glue driver.
(select ISDN_CAPI_CAPIDRV.)
Say N to build the old native ISDN4Linux variant.
If unsure, say Y.

base for connection to your system.
This will build a module called "bas_gigaset".

Say M here if you want to connect to the Gigaset base via DECT

This will build a module called "usb_gigaset".

Say M here if you want to connect to the Gigaset base via DECT
using a Gigaset M101 (Sinus 45 Data 1) RS232 DECT device.

bool "Gigaset debugging"
help
This enables debugging code in the Gigaset drivers.
If in doubt, say yes.
