tty: Added a CONFIG_TTY option to allow removal of TTY

2013-01-19T00:15:27+00:00

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.

isdn: Make CONFIG_ISDN depend on CONFIG_NETDEVICES

2012-11-07T23:59:26+00:00

It doesn't make much sense to enable ISDN services if you don't
intend to connect to a network. Therefore insisting that ISDN
depends on NETDEVICES seems logical. We can then remove any
guards mentioning NETDEVICES inside all subordinate drivers.

This also has the nice side-effect of fixing the warning below
when ISDN_I4L && !CONFIG_NETDEVICES at compile time.

This patch fixes:
drivers/isdn/i4l/isdn_common.c: In function ‘isdn_ioctl’:
drivers/isdn/i4l/isdn_common.c:1278:8: warning: unused variable ‘s’ [-Wunused-variable]

isdn: fix a few Kconfig imperfections

2010-02-22T23:45:53+00:00

1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI.
2. The MISDN config option appeared between ISDN_I4L and the I4L hardware
   driver options; move it to a less irritating place.
3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so
   move it from the I4L section to the general section.
4. ISDN_HDLC is now also used by drivers outside I4L.  Move it from the
   I4L section to the general section, too.

ISDN: Make isdnhdlc usable for other ISDN drivers

2009-07-25T18:15:21+00:00

isdnhdlc is useful for other ISDN drivers as well.
Move the include file to a central location and the source
to the central isdn location.

gigaset: move up Kconfig inclusion point

2009-05-18T03:51:26+00:00

In preparation for porting to kernel CAPI subsystem, include the
Gigaset driver's Kconfig directly from ISDN's instead of I4L's.

Impact: Kconfig reorganisation, no functional change

Add mISDN driver

2008-07-26T23:46:33+00:00

mISDN is a new modular ISDN driver, in the long term it should replace
the old I4L driver architecture for passiv ISDN cards.

Use menuconfig objects - CONFIG_ISDN_I4L

2007-07-22T00:49:17+00:00

Remove a menu statement and several dependencies from the Kconfig files in
the drivers/isdn tree as they have become unnecessary by the transformation
of CONFIG_ISDN from "menu, config" into "menuconfig".
