Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)
When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:
a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.
C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).
Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.
Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

Fix up trivial conflict in drivers/input/keyboard/Kconfig (two entries
added next to each other - one from the davinci merge, one from the
input merge)
KBUILD_MODNAME normalizes "-" to "_". This is non-obvious and results in
the id name for ADP5588 being "adp5588_keys" while the other supported id
is "adp5587-keys". So avoid this define and use an explicit string as the
id name.

Program keyboard controller to generate a wake-up request on events and
on long key presses. It will not generate wake-up requests on timeouts
since driver code does not handle them.
This allows keyboard to wake-up OMAP from suspend.

They've been introduced by 987a6c02 ("Input: switch to input_abs_*()
access functions") and they appear to be some kind of debug left-over.
[Dmitry Torokhov: these are my fault - I added XX prefixes in places where
I wanted to do additional review of the code but failed to actually do
that in these particular instances.]
