    [PATCH] isdn4linux: Siemens Gigaset drivers - Kconfigs and Makefiles · 0a34eb8f

    The following patches add drivers for the Siemens Gigaset 3070 family of ISDN
    DECT PABXes connected via USB, either directly or over a DECT link using a
    Gigaset M105 or compatible DECT data adapter.  The devices are integrated as
    ISDN adapters within the isdn4linux framework, supporting incoming and
    outgoing voice and data connections, and also as tty devices providing access
    to device specific AT commands.
    Supported devices include models 3070, 3075, 4170, 4175, SX205, SX255, and
    SX353 from the Siemens Gigaset product family, as well as the technically
    identical models 45isdn and 721X from the Deutsche Telekom Sinus series.
    Supported DECT adapters are the Gigaset M105 data and the technically
    identical Gigaset USB Adapter DECT, Sinus 45 data 2, and Sinus 721 data (but
    not the Gigaset M34 and Sinus 702 data which advertise themselves as CDC-ACM
    These drivers have been developed over the last four years within the
    SourceForge project http://sourceforge.net/projects/gigaset307x/.  They are
    being used successfully in several installations for dial-in Internet access
    and for voice call switching with Asterisk.
    This is our second attempt at submitting these drivers, taking into account
    the comments we received to our first submission on 2005-12-11.
    The patch set adds three kernel modules:
    - a common module "gigaset" encapsulating the common logic for
      controlling the PABX and the interfaces to userspace and the
      isdn4linux subsystem.
    - a connection-specific module "bas_gigaset" which handles
      communication with the PABX over a direct USB connection.
    - a connection-specific module "usb_gigaset" which does the same
      for a DECT connection using the Gigaset M105 USB DECT adapter.
    We also have a module "ser_gigaset" which supports the Gigaset M101 RS232 DECT
    adapter, but we didn't judge it fit for inclusion in the kernel, as it does
    direct programming of a i8250 serial port.  It should probably be rewritten as
    a serial line discipline but so far we lack the neccessary knowledge about
    writing a line discipline for that.
    The drivers have been working with kernel releases 2.2 and 2.4 as well as 2.6,
    and although we took efforts to remove the compatibility code for this
    submission, it probably still shows in places.  Please make allowances.
    This patch:
    Prepare the kernel build infrastructure for addition of the Gigaset ISDN
    drivers.  It creates a Makefile and Kconfig file for the Gigaset driver and
    hooks them into those of the isdn4linux subsystem.  It also adds a MAINTAINERS
    entry for the driver.
    This patch depends on patches 2 to 9 of the present set, as without the actual
    source files, activating the options added here will cause the kernel build to
