Alps GlidePoint driver for synaptics.

[David DEMELIER <demelier.david%gmail.com@localhost>]

Hello tech-kern@

I posted a PR (#41533) because my touchpad wasn't supported on my HP
Pavilion dv2899, I recently understand that the touchpad is not a
regular synaptic touchpad but an Alps GlidePoint and for now there is
no support of it. Is anyone working on a Alps driver for pms(4) ?

This is the touchpad :

I: Bus=0011 Vendor=0002 Product=0008 Version=7321
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input6
U: Uniq=
H: Handlers=mouse2 event6
B: EV=f
B: KEY=420 0 70000 0 0 0 0 0 0 0 0
B: REL=3
B: ABS=1000003

Cheers,
David.
