commit fb4f8f568a upstream.
The touchpad on the GIGABYTE U2442 not only stops communicating when we try
to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS
versions also when we set bit 1 (enable two finger mode auto correct).
I've asked the original reporter of:
https://bugzilla.kernel.org/show_bug.cgi?id=61151
To check that not setting bit 1 does not lead to any adverse effects on his
model / BIOS revision, and it does not, so this commit fixes the touchpad
not working on these versions by simply never setting bit 1 for laptop
models with the no_hw_res quirk.

commit cd9e83e275 upstream.
At least the Dell Vostro 5470 elantech *clickpad* reports right button
clicks when clicked in the right bottom area:
https://bugzilla.redhat.com/show_bug.cgi?id=1103528
This is different from how (elantech) clickpads normally operate, normally
no matter where the user clicks on the pad the pad always reports a left
button event, since there is only 1 hardware button beneath the path.
It looks like Dell has put 2 buttons under the pad, one under each bottom
corner, causing this.
Since this however still clearly is a real clickpad hardware-wise, we still
want to report it as such to userspace, so that things like finger movement
in the bottom area can be properly ignored as it should be on clickpads.
So deal with this weirdness by simply mapping a right click to a left click
on elantech clickpads. As an added advantage this is something which we can
simply do on all elantech clickpads, so no need to add special quirks for
this weird model.

commit 6d396ede22 upstream.
The T540p has a touchpad with pnp-id LEN0034, all the models with this
pnp-id have the same min/max values, except the T540p where the values are
slightly off. Fix them to be identical.
This is a preparation patch for simplifying the quirk table.

commit 36189cc3cd upstream.
The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"
Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

commit 3d725caa9d upstream.
After issuing ATKBD_CMD_RESET_DIS, keyboard on some LG laptops stops
working. The workaround is to stop issuing ATKBD_CMD_RESET_DIS commands.
In order to keep changes in atkbd driver to the minimum we check DMI
signature and only skip ATKBD_CMD_RESET_DIS if we are running on LG
LW25-B7HV or P1-J273B.

keyreset now registers a keycombo driver that acts as the old
keyreset driver acted.

Keycombo lets you provide a key up and key down function, and an
optional time delay for key down. The driver will call the key
down function after the specified key combo has been held for the
speicified time delay. After you release the combo, if the key down
has happened, it calls key up.

commit 46a2986ebb upstream.
We expect that all the Haswell series will need such quirks, sigh.
The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
with the same min/max issue.
The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.
The X1 and T431s share a PnPID with the T540p, but the reported ranges are
closer to those of the T440s.
HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
S1 Yoga and X1 are written by Benjamin Tissoires.
Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
X240, X1 uses the same touchpad as the T440.

If your sdk's lcd is f402, plese make rk3288-tb1.img and you need to
define TB1_USE_F402 in drivers/input/touchscreen/vtl_ts/chip.c and
drivers/input/touchscreen/vtl_ts/vtl_ts.h to make tp work fine.
commit 6797b39e6f upstream.
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:
