Input: cyapa - fix setting suspend scan rate

2015-04-20T17:30:09+00:00

The suspend scan rate value should not exceed 1000, unfortunately when
implementing the limit we used max_t instead of min_t, causing the value to
be at least 1000.

Input: elan_i2c - fix calculating number of x and y traces.

2015-04-20T17:30:09+00:00

According to Elan's firmware engineers we should not be subtracting 1 form
the raw number of x and y traces so that the pitch size is correct. For
example, if the touchpad x resolution is 2800 and x trace number is 20,
the pitch size of x should be 2800/20 = 140, not 2800/19 = 147.36.

Input: elan_i2c - report hovering contacts

2015-04-20T17:28:30+00:00

When hover is detected report ABS_MT_DISTANCE as 1; for active contacts
the distance is reported as 0.

Input: add vmmouse driver

2015-04-14T21:29:03+00:00

VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU
guests.  By removing the guest cursor and using the host as a guest cursor
the cursor movement appears instant although in reality there is some lag.
To be able to do this, the host's view of the cursor position must exactly
match the guest's view and an absolute pointer device is needed. Enter the
VMMouse. While the VMMouse driver has historically been an Xorg user-space
driver, implementing it as a kernel imput driver enables rootless Xorg and
new compositing display servers for VMware guests.

Prepare first round of input updates for 4.1 merge window.

Input: alps - non interleaved V2 dualpoint has separate stick button bits

2015-04-12T22:44:15+00:00

Non interleaved V2 dualpoint touchpad / stick combos have separate stick
button bits in the touchpad packets, if we do not check these then the
trackpoint buttons will not work when using the touchpad, and when pressed
when the user starts using the touchpad will report a release event even
though the button is still pressed.

This commit fixes this by checking the separate bits, note that we simply
combine the buttons, since the hardware does the same when using the touchpad
buttons with the trackpoint, so we do not have enough information to properly
separate them.

Input: alps - fix touchpad buttons getting stuck when used with trackpoint

2015-04-12T22:39:41+00:00

When the left touchpad button gets pressed, and then the trackpoint is
moved, and then the button is released, the following happens:

1) touchpad packet is received, touchpad evdev node reports BTN_LEFT 1

2) pointing stick packet is received, the hw will report a BTN_LEFT 1 in
   this packet because when the trackstick is active it communicates the
   combined touchpad + pointing stick buttons in the trackstick packet,
   since alps_report_bare_ps2_packet passes NULL (*) for the dev2 parameter
   to alps_report_buttons the combining is not detected and the
   pointing stick evdev node will also report BTN_LEFT 1

3) on release of the button a pointing stick packet with BTN_LEFT 0 is
   received and the pointing stick evdev node will report BTN_LEFT 0

Note how because of the passing as NULL for dev2 the touchpad evdev node
will never send BTN_LEFT 0 in this scenario leading to a stuck mouse button.

This is a regression in 4.0 introduced by commit 04aae283ba6a8
("Input: ALPS - do not mix trackstick and external PS/2 mouse data")

This commit fixes this by passing in the touchpad evdev as dev2 parameter
when calling alps_report_buttons for the pointingstick on alps v2 devices,
so that alps_report_buttons correctly detect that we're already reporting
the button as pressed via the touchpad evdev node, and will also send the
release event there.
