staging: dgnc: add dgnc digi driver
This patch adds the DGNC driver. This is a TTY Serial Port Driver for the Digi International Neo and Classic PCI based product line by Digi International <http://www.digi.com>. This driver isn't hooked up to the build system because it doesn't build, it merely adds the driver written by Digi to the kernel tree so that it can be cleaned up and fixed up properly over time.

* Description:
|
||||
*
|
||||
* Describes the private structures used to manipulate the "special"
|
||||
* proc constructs (not read-only) used by the Digi Neo software.
|
||||
* The concept is borrowed heavily from the "sysctl" interface of
|
||||
* the kernel. I decided not to use the structures and functions
|
||||
* provided by the kernel for two reasons:
|
||||
*
|
||||
* 1. Due to the planned use of "/proc" in the Neo driver, many
|
||||
* of the functions of the "sysctl" interface would go unused.
|
||||
* A simpler interface will be easier to maintain.
|
||||
*
|
||||
* 2. I'd rather divorce our "added package" from the kernel internals.
|
||||
* If the "sysctl" structures should change, I will be insulated
|
||||
* from those changes. These "/proc" entries won't be under the
|
||||
* "sys" tree anyway, so there is no need to maintain a strict
|
||||
* dependence relationship.
