ELAN0605 has been confirmed to be a variant of ELAN0600, which is
blacklisted in the hid-core to be managed by elan_i2c. This device can be
found in Lenovo ideapad 310s (80U4000).

Instead of using custom method of "passing" extended buttons from the

The tracksticks on the Lenovo thinkpads have their buttons connected
through the touchpad device. We already fixed that in synaptics.c, but
when we switch the device into RMI4 mode to have proper support, the
pass-through functionality can't deal with them easily.
We add a new PS/2 flag and protocol designed for psmouse. The RMI4 F03
pass-through can then emit a special set of commands to notify psmouse the
state of the buttons.
This patch implements the protocol in psmouse, while an other will
do the same for rmi4-f03.

Using counter based retry loops for peripherals results in the delay
being significantly overrun during high-load situations where delay
functions tend to be vary imprecise and overrun there timeouts. So
condition the termination on the actual condition of 2s for the
re-calibration to have been successful.
As this is a very long delay there is no advantage in using
high-resolution timers thus switching this to msleep().

A minus character was lost in commit 23fce365, causing the Y axis to be

the pointer to move down, and vice versa.) Restore the lost minus.

msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, retry logic, etc.
Thus, change msleep to usleep_range for precise wakeups.

The return value of alps_get_pkt_id_ss4_v2() should really be "enum
SS4_PACKET_ID", not "unsigned char". Correct this.
Also, most of the Alps SS5 (SS4 v2) packet byte parsing code is implemented
using macros, but there are a few places where bytes are directly
manipulated in alps.c. For consistency, migrate the rest of these to
macros.

The current Alps SS5 (SS4 v2) code generates bogus TouchPad events when
TrackStick packets are processed.
This causes the xorg synaptics driver to print
"unable to find touch point 0" and
"BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'"
messages. It also causes unexpected TouchPad button release and re-click
event sequences if the TrackStick is moved while holding a TouchPad
button.
This commit corrects the problem by adjusting alps_process_packet_ss4_v2()
so that it only sends TrackStick reports when processing TrackStick
packets.

BYD automatic protocol detection is extremely unreliable and is often
triggers false positives on regular mice, Sentelic touchpads, and other
devices. BYD has several documents that have recommended detection
sequence, but they conflict with each other and, as far as I can see, still
would not produce unique enough output to reliably differentiate BYD from
other PS/2 devices.
OEMs sourcing BYD devices also do not do us any favors by not supplying any
reasonable DMI data and instead leaving turds like "To Be Filled By O.E.M."
in place of vendor data, or "System Serial Number" as serial number.
On top of that BYD is not truly modern multitouch controller, but rather a
single-touch transitional device that only reports absolute coordinates at
the beginning of finger contact and then reverts to reporting
displacements, and thus not very precise; the only benefit from using BYD
mode vs the legacy PS/2 mode is possibility of edge scrolling.
Given the above, and the fact that BYD devices are somewhat uncommon, let's
disable automatic detection of BYD devices. Users who know they have BYD
trackpads or want to experiment can attempt to activate BYD protocol via
sysfs:
echo -n "byd" > /sys/bus/serio/devices/serio1/drvctl

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with

i2c_smbus_read_block_data() returns negative errno else the number of
data bytes in the slave's response.
Checking for error not null means the function always fails if the device

actually read those 3 bytes.

The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.
This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port
on its own.
The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs. It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

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.
