The Windows driver's settings dialog contains a visualization of the
regions for the hardware edge scrolling capability, which uses a
temporarily-enabled limited-resolution absolute mode.
This patch enables this during normal operation, and combines the
absolute packets with the existing relative packets to provide
accurate absolute position and touch reporting.
It also adds documentation for all known gesture packets and
initialization commands.

When changing the scan rate as part of runtime-resume process we may lose
some of the events, because:
1) for gen3 trackpads, the driver must msleep() some time to ensure that
the device is ready to accept next command;
2) for gen5 and later trackpads, the queue dumping function will simply
ignore the events when waiting for the set power mode command response.
The solution is to keep polling and report those valid events when the set
power mode command is in progress.

Driver for the BYD BTP10463 touchpad, found in PC Specialist `Lafite'
laptops. This patch sends the magic command sequence which causes the
touchpad to stream intellimouse-style packets.
Gestures are detected inside the touchpad, and exposed as special
values in the Z component of each packet - absolute coordinates are
not supported, even in the Windows driver. At present, this supports
two-finger vertical and horizontal scrolling, and provides the
framework to expose the other gestures it can recognize.

When using a protocol v2 or v3 hardware, elantech uses the function
elantech_report_semi_mt_data() to report data. This devices are rather
creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid
touch is reported.
Anyway, userspace (libinput) is now confused by these (0,0) touches,
and detect them as palm, and rejects them.
Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW")
was sufficient enough for xf86-input-synaptics and libinput before it has
palm rejection. Now we need to actually tell libinput that this device is
a semi-mt one and it should not rely on the actual values of the 2 touches.

This patch adds detection of trackstick for v7 protocol devices. Code in
this patch is used in official Dell touchpad linux drivers for Dell models:
Dell Latitude E5250/5250, E5450/5450, E5550/5550
Detection code and base reg for alps v3 rushmore and v7 devices is exacly
same.

PS/2 protocol is slow, and using it with pass-through port (where we
encapsulate PS/2 into PS/2) is slower yet so it takes quite a bit of time
to do full protocol discovery for device attached to a pass-through port.
However, so far we have not see anything but trackpoints or basic PS/2
mice on pass-through ports, so let's limit protocols that we probe there
to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol,
and avoid other extended protocols, such as Synaptics, ALPS, etc.

In preparation of limiting protocols that we try on pass-through ports,
let's rework initialization code and factor common code into
psmouse_try_protocol() that accepts protocol type (instead of detec()
function pointer) and can, for most protocols, perform both detection and
initialization.
Note that this removes option of forcing Lifebook protocol on devices that
are not recognized by lifebook_detect() as having the hardware, but I do
not recall anyone using this option.

When Cypress protocol support is disabled cypress_init() is a stub that
always returns -ENOSYS, so there is not point in testing for
CONFIG_MOUSE_PS2_CYPRESS after we decided that we are dealing with a
Cypress device. Also, we should only be calling cypress_detect() when
set_properties argument is "true", like with other protocols.
There is a slight change in behavior to make follow-up patches more
uniform: when we detect Cypress but its initialization fails, instead of
immediately returning PSMOUSE_PS2 protocol we now continue trying
IntelliMouse [Explorer]. Given that Cypress devices only have issue with
Sentelic probes probing Imtellimouse should be safe.

The fact that we were calling focaltech_init() even when Focaltech support
is disabled was confusing. Rearrange the code so that if support is
disabled we continue to fall through the rest of protocol probing code
until we get to full reset that Focaltech devices need to work properly.
Also, replace focaltech_init() with a stub now that it is only called when
protocol is enabled.

Previously the "vendor" and "product" IDs for the elan_i2c driver simply
reported 0000. This patch modifies the elan_i2c driver to include the
Elan vendor ID and the touchpad's product id under
input/input*/{vendor,product}.
Specifically, this is to allow us to apply a generic Elan gestures config
that will apply to all Elan touchpads on ChromeOS. These configs match to
input devices in various ways, but one major way is by matching on vendor
ID. Adding this patch allows the default Elan touchpad config to be
applied to Elan touchpads in this kernel by matching on devices that have
vendor ID 04f3.
Note that product ID is also available via custom sysfs entry "product_id"
as well.

button bits
commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has
separate stick button bits") assumes that all alps v2 non-interleaved
dual point setups have the separate stick button bits.
Later we limited this to Dell laptops only because of reports that this
broke things on non Dell laptops. Now it turns out that this breaks things
on the Dell Latitude D600 too. So it seems that only the Dell Latitude
D420/430/620/630, which all share the same touchpad / stick combo,
have these separate bits.
This patch limits the checking of the separate bits to only these models
fixing regressions with other models.

Bit 2 of the mode byte has dual meaning: it can disable reporting of
gestures when touchpad works in Relative mode or normal Absolute mode,
or it can enable so called Extended W-Mode when touchpad uses enhanced
Absolute mode (W-mode). The extended W-Mode confuses our driver and
causes missing button presses on some Thinkpads (x250, T450s), so let's
make sure we do not enable it.
Also, according to the spec W mode "... bit is defined only in Absolute
mode on pads whose capExtended capability bit is set. In Relative mode and
in TouchPads without this capability, the bit is reserved and should be
left at 0.", so let's make sure we respect this requirement as well.
