The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad.
However, these new Synaptics devices report bad axis ranges.
Under Windows, it is not a problem because the Windows driver uses RMI4
over SMBus to talk to the device. Under Linux, we are using the PS/2
fallback interface and it occurs the reported ranges are wrong.

Of course, it would be too easy to have only one range for the whole
series, each touchpad seems to be calibrated in a different way.

We can not use SMBus to get the actual range because I suspect the firmware
will switch into the SMBus mode and stop talking through PS/2 (this is the
case for hybrid HID over I2C / PS/2 Synaptics touchpads).

So as a temporary solution (until RMI4 land into upstream), start a new
list of quirks with the min/max manually set.

The cypress PS/2 trackpad models supported by the cypress_ps2 driver
emulate BTN_RIGHT events in firmware based on the finger position, as part
of this no motion events are sent when the finger is in the button area.

The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that
BTN_RIGHT events should be emulated in userspace, which is not necessary
in this case.

When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion
event before propagating the button event higher up the stack, as it needs
current abs x + y data for its BTN_RIGHT emulation. Since in the
cypress_ps2 pads don't report motion events in the button area, this means
that clicks in the button area end up being ignored, so
INPUT_PROP_BUTTONPAD actually causes problems for these touchpads, and
removing it fixes:

The wrong register bit of the DA9052/3 PMIC registers was
used to determine the status on the ONKEY.

Also a failure in reading the status register will no longer
result in the work queue being rescheduled as that would result
in a (potentially) endless retry.

As discussed here: http://ez.analog.com/message/35852, the 5587 revC and
5588 revB spec sheets contain a mistake in the GPIO_DAT_STATx register
description.

According to R.Shnell at ADI, as well as my own observations, it should
read: "GPIO data status (shows GPIO state when read for inputs)".

This commit changes the get value function accordingly.

The driver can't deal with two entries its keymap having the same keycode.
When this happens it will get confused about whether the key is down or up
and will cause some screwy behavior.

We need to have two entries for KEY_BACKSLASH to handle US and UK
keyboards. Specifically:
* On the US keyboard the backslash key (above enter) is r3 c11 and is
  supposed to be reported as BACKSLASH.
* On the UK keyboard the # key (left of enter) is r4 c10 and is
  supposed to be reported as BACKSLASH.
* On the UK keyboard the \ key (left of Z) is r2 c7 and is supposed to
  be reported as KEY_102ND.

Note that both keyboards (US and UK) have only one physical backslash
key so the constraint that each physical key should have its own keycode
still stands.

The current assumption in the elantech driver that hw version 3 touchpads
are never clickpads and hw version 4 touchpads are always clickpads is
wrong.

There are several bug reports for this, ie:
https://bugzilla.redhat.com/show_bug.cgi?id=1030802
http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux

I've spend a couple of hours wading through various bugzillas, launchpads
and forum posts to create a list of fw-versions and capabilities for
different laptop models to find a good method to differentiate between
clickpads and versions with separate hardware buttons.

Which shows that a device being a clickpad is reliable indicated by bit 12
being set in the fw_version. I've included the gathered list inside the
driver, so that we've this info at hand if we need to revisit this later.
