Pull HID updates from Jiri Kosina:
- quite a few firmware fixes for RMI driver by Andrew Duggan
- huion and uclogic drivers have been substantially overlaping in
functionality laterly. This redundancy is fixed by hid-huion driver
being merged into hid-uclogic; work done by Benjamin Tissoires and
Nikolai Kondrashov
- i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg
- Some of the quirks, that got separated into individual drivers, have
historically had EXPERT dependency. As HID subsystem matured (as
well as the individual drivers), this made less and less sense. This
dependency is now being removed by patch from Jean Delvare
- Logitech lg4ff driver received a couple of improvements for mode
switching, by Michal Malý
- multitouch driver now supports clickpads, patches by Benjamin
Tissoires and Seth Forshee
- hid-sensor framework received a substantial update; namely support
for Custom and Generic pages is being added; work done by Srinivas
Pandruvada
- wacom driver received substantial update; it now supports
i2c-conntected devices (Mika Westerberg), Bamboo PADs are now
properly supported (Benjamin Tissoires), much improved battery
reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng)
- small assorted fixes and device ID additions

The case occurred recently with a touchscreen using twice a slot during a
single EV_SYN event:
E: 0.288415 0000 0000 0000 # ------------ SYN_REPORT (0) ----------
E: 0.296207 0003 002f 0000 # EV_ABS / ABS_MT_SLOT 0

E: 0.296207 0000 0000 0000 # ------------ SYN_REPORT (0) ----------
This occurred because while having already slots 0 and 1 assigned, the
touchscreen sent:
0.293377 Tip Switch: 0 | Contact Id: 0 | X: 539 | Y: 1960 | Contact Count: 3
0.294783 Tip Switch: 1 | Contact Id: 1 | X: 908 | Y: 1062 | Contact Count: 0
0.296187 Tip Switch: 1 | Contact Id: 2 | X: 1566 | Y: 861 | Contact Count: 0
Slot 0 is released correclty, but when we look for Contact ID 2, the slot
0 is then picked up again because it is marked as inactive (trackingID < 0).
This is wrong, and we should not reuse a slot in the same frame.
The test should also check for input_mt_is_used().
In addition, we need to initialize mt->frame to an other value than 0.
With mt->frame being 0, all slots are tags as currently used, and so
input_mt_get_slot_by_key() would return -1 for all requests.

"Updates for the input subsystem - two more tweaks for ALPS driver to

On V2 devices the DualPoint Stick reports bare packets, these should be
reported via the "AlpsPS/2 ALPS DualPoint Stick" dev2 evdev node, which also
has the INPUT_PROP_POINTING_STICK propbit set.
Note that since there is no way to distinguish these packets from an external
PS/2 mouse (insofar as these laptops have an external PS/2 port) this means
that we will be reporting PS/2 mouse events via this evdev node too, as we've
been doing in kernel 3.19 and older.
This has been tested on a Dell Latitude D620 and a Dell Latitude E6400,
which both have a V2 touchpad + a DualPoint Stick which reports bare packets.

Bare packets should be reported via the same evdev device independent on
whether they are detected on the beginning of a packet or in the middle
of a packet.
This has been tested on a Dell Latitude E6400, where the DualPoint Stick
reports bare packets, which get reported via dev3 when the touchpad is
idle, and via dev2 when the touchpad and stick are used simultaneously.
This commit fixes this inconsistency by always reporting bare packets via
dev3. Note that since the come from a DualPoint Stick they really should be
reported via dev2, this gets fixed in a later commit.

Its ClickPad shares PNP ID "LEN2006" with the one in model E540 which is
already handled by the driver (both are Haswell iterations of the Edge
line, launched in 2014) but the dimensions it reports are different:
$ sudo ./touchpad-edge-detector /dev/input/event3
Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event3
Move one finger around the touchpad to detect the actual edges
Kernel says: x [1472..5044], y [1408..3398]
Touchpad sends: x [1024..5045], y [2457..4832] /^C
Fortunately we can use the board ID, which is also different, to
distinguish among them.

Slot 0 and 1 gets inverted in the second report above, which
introduces a cursor jump. The problem is that this cursor jump is
often enough to leave the current widget, and X sends the
scrolling events to whoever is now under the cursor.

Lenovo X250 has a PnpID of LEN0046, but it does not have the top software
button requirement.
For the record, Lenovo T450s and W541 have a PnpID of LEN200f and LEN004a,
so they are not on the top software button list.

Lenovo decided to switch back to physical buttons for the trackstick on
their latest series. The PNPId list was provided before they reverted back
to physical buttons, so it contains the new models too. We can know from
the touchpad capabilities that the touchpad has physical buttons, so
removing the ids from the list is not mandatory. It is still nicer to
remove the wrong ids, so start by removing the X1 Carbon 3rd gen, with the
PNPId of LEN0048.

The 2015 series of the Lenovo thinkpads added back the hardware buttons on
top of the touchpad for the trackstick.
Unfortunately, they are wired to the touchpad, and not the trackstick.
Thus, they are seen as extra buttons from the kernel point of view.
This leads to a problem in user space because extra buttons on synaptics
devices used to be used as scroll up/down buttons. So in the end, the
experience for the user is scroll events for buttons left and right when
using the trackstick. Yay!
Fortunately, the firmware advertises such behavior in the extended
capability $10, and so we can re-route the buttons through the pass-through
interface.

The 2015 series of the Lenovo thinkpads added back the hardware buttons on
top of the touchpad for the trackstick.
Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons"
touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay!
Instead of manually removing each of the new ones, or hoping that we know
all the current ones, we can consider that the PNPIDs list that were given
contains touchpads that have the trackstick buttons, either physically
wired to them, or emulated with the top software button property.
Thanks to the extra buttons capability in query $10, we can reliably detect
the physical buttons from the software ones, and so we can remove the
TOPBUTTONPAD property even if it was declared as such.

On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle
button of the trackstick (attached to the touchpad serio device, of course)
seems to get lost.
Actually, the touchpads reports 3 extra buttons, which falls in the switch
below to the '2' case. Let's handle the case of odd numbers also, so that
the middle button finds its way back.

Post-2013 Lenovo laptops provide correct min/max dimensions, which are
different with the ones currently quirked. According to
https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids
are assigned in the post-2013 touchpads:
t440p/t440s: LEN0036 -> 2964/2962
t540p: LEN0034 -> 2964
Using 2961 as the common minimum makes these 3 laptops OK. We may need
to update those values later if other pnp_ids has a lower board_id.

Add a min/max range for board ids to the min/max coordinates quirk. This
makes it possible to restrict quirks to specific models based upon their
board id. The define ANY_BOARD_ID (0) serves as a wild card.

Query the min dimensions even if the check

firmware version 8.1 is safe.
With that we don't need quirks for post-2013 models anymore as they expose

Apparently, the threshold for large contact area seems to be rather low on
some devices, causing the touchpad to frequently freeze during normal
usage. Because we do now know how we are supposed to use the value in
question, this commit just drops the related code completely.

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.
Currently, plat->irqtype is only set to IRQF_TRIGGER_FALLING. This
patch sets the ONESHOT flag directly in request_threaded_irq() to
enforce the flag without being affected by future changes to
plat->irqtype.

The sun4i-ts driver has had a dependency on the thermal code
with the addition of the thermal zone sensor support, but this
is not currently enforced in Kconfig, so with TOUCHSCREEN_SUN4I=y,
THERMAL=m and THERMAL_OF=y we get
drivers/built-in.o: In function `sun4i_ts_remove':
:(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister'
drivers/built-in.o: In function `sun4i_ts_probe':
:(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register'
:(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'
We need the dependency on THERMAL in order to ensure that this
driver becomes a loadable module if the thermal support itself
is modular, while the dependency on THERMAL_OF is a runtime
dependency and the driver will still build if it is missing.
It is entirely possible to build sun4i-ts without THERMAL_OF
just to use the hwmon sensors and/or touchscreen.

If *data_size is non-zero, and idac_data_type contains an unknown type,
max_element_cnt and offset will be uninitialized, and the loop will

However, this cannot happen (for now), as there's a test for unknown
