George Pantalos 3b7e09fad9 Input: ALPS - add semi-MT support for v4 protocol
This patch adds semi-MT support for ALPS v4 protocol touchpads.
It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
support. Three packets are required to assemble and process the MT
data. ST events are reported at once to avoid latency. If there
were two contacts or more, report MT data instead of ST events.

Thanks to Seth Forshee for providing most of the code, guidance
and insight for producing this patch.

Seth Forshee 25bded7cd6 Input: ALPS - add support for protocol versions 3 and 4
This patch adds support for two ALPS touchpad protocols not
supported currently by the driver, which I am arbitrarily naming
version 3 and version 4. Support is single-touch only at this time,
although both protocols are capable of limited multitouch support.

Thanks to Andrew Skalski, who did the initial reverse-engineering
of the v3 protocol.

Seth Forshee fa629ef522 Input: ALPS - add protocol version field in alps_model_info
In preparation for adding support for more ALPS protocol versions,
add a field for the protocol version to the model info instead of
using a field in the flags. OLDPROTO and !OLDPROTO are now called
version 1 and version 2, repsectively.

Sebastian Kapfer 1d9f26262a Input: ALPS - add interleaved protocol support (Dell E6x00 series)
Properly handle version of the protocol where standard PS/2 packets
from trackpoint are stuffed into middle (byte 3-6) of the standard
ALPS packets when both the touchpad and trackpoint are used together.

The patch is based on work done by Matthew Chapman and additional
research done by David Kubicek and Erik Osterholm:

Many thanks to David Kubicek for his efforts in researching fine points
of this new version of the protocol, especially interaction between pad
and stick in these models.

Andres Salomon 55e3d9224b Input: psmouse - allow disabing certain protocol extensions
Allow ALPS, LOGIPS2PP, LIFEBOOK, TRACKPOINT and TOUCHKIT protocol
extensions of psmouse to be disabled during compilation. This will
allow users save some memory when they are sure that they will only
use a certain type of mice.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
