1aae31c830 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
 "The main change is that we now publish "firmware ID" for the serio
  devices to help userspace figure out the kind of touchpads it is
  dealing with: i8042 will export PS/2 port's PNP IDs as firmware IDs.

  You will also get more quirks for Synaptics touchpads in various
  Lenovo laptops, a change to elantech driver to recognize even more
  models, and fixups to wacom and couple other drivers"

ae4bedf067 Input: elantech - add support for newer elantech touchpads
Newer elantech touchpads are not recognized by the current driver, since it
fails to detect their firmware version number. This prevents more advanced
touchpad features from being usable such as two-finger scrolling. This
patch allows newer touchpads to be detected and be fully functional. Tested
on Sony Vaio SVF13N17PXB.

46a2986ebb Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1
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.

0456c66f4e Input: serio - add firmware_id sysfs attribute
serio devices exposed via platform firmware interfaces such as ACPI may
provide additional identifying information of use to userspace.

We don't associate the serio devices with the firmware device (we don't
set it as parent), so there's no way for userspace to make use of this
information.

We cannot change the parent for serio devices instantiated though a
firmware interface as that would break suspend / resume ordering.

Therefore this patch adds a new firmware_id sysfs attribute so that
userspace can get a string from there with any additional identifying
information the firmware interface may provide.

The 0xEC sensor is used in multiple tablet PCs and curiously has versions
that report 256 levels of pressure (Samsung Slate 7) as well as versions
that report 1024 levels (Lenovo Thinkpad Yoga).  To allow both versions to
work properly, we allow the value of HID_USAGE_PRESSURE reported to
override pressure_max.

5866d9e3b7 Input: wacom - use full 32-bit HID Usage value in switch statement
A HID Usage is a 32-bit value: an upper 16-bit "page" and a lower 16-bit
ID. While the two halves are normally reported seperately, only the
combination uniquely idenfifes a particular HID Usage.

The existing code performs the comparison in two steps, first performing a
switch on the ID and then verifying the page within each case. While this
works fine, it is very akward to handle two Usages that share a single ID,
such as HID_USAGE_PRESSURE and HID_USAGE_X because the case statement can
only have a single identifier.

To work around this, we now check the full 32-bit HID Usage directly rather
than first checking the ID and then the page.  This allows the switch
statement to have distinct cases for e.g. HID_USAGE_PRESSURE and
HID_USAGE_X.

06491e84f0 Input: da9055_onkey - remove use of regmap_irq_get_virq()
Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device.  Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g.  0, 1, 2, 3, etc).

This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening.

4dedde7c7a ACPI and power management updates for 3.15-rc1
- Device PM QoS support for latency tolerance constraints on systems with
    hardware interfaces allowing such constraints to be specified.  That is
    necessary to prevent hardware-driven power management from becoming
    overly aggressive on some systems and to prevent power management
    features leading to excessive latencies from being used in some cases.
 
  - Consolidation of the handling of ACPI hotplug notifications for device
    objects.  This causes all device hotplug notifications to go through
    the root notify handler (that was executed for all of them anyway
    before) that propagates them to individual subsystems, if necessary,
    by executing callbacks provided by those subsystems (those callbacks
    are associated with struct acpi_device objects during device
    enumeration).  As a result, the code in question becomes both smaller
    in size and more straightforward and all of those changes should not
    affect users.
 
  - ACPICA update, including fixes related to the handling of _PRT in cases
    when it is broken and the addition of "Windows 2013" to the list of
    supported "features" for _OSI (which is necessary to support systems
    that work incorrectly or don't even boot without it).  Changes from
    Bob Moore and Lv Zheng.
 
  - Consolidation of ACPI _OST handling from Jiang Liu.
 
  - ACPI battery and AC fixes allowing unusual system configurations to
    be handled by that code from Alexander Mezin.
 
  - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.
 
  - ACPI fan and thermal optimizations related to system suspend and resume
    from Aaron Lu.
 
  - Cleanups related to ACPI video from Jean Delvare.
 
  - Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan Tianyu,
    Paul Bolle, Tomasz Nowicki.
 
  - Intel RAPL (Running Average Power Limits) driver cleanups from Jacob Pan.
 
  - intel_pstate fixes and cleanups from Dirk Brandewie.

Merge tag 'pm+acpi-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the
     list of supported "features" for _OSI (which is necessary to
     support systems that work incorrectly or don't even boot without
     it).  Changes from Bob Moore and Lv Zheng.

   - Consolidation of ACPI _OST handling from Jiang Liu.

   - ACPI battery and AC fixes allowing unusual system configurations to
     be handled by that code from Alexander Mezin.

   - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.

   - ACPI fan and thermal optimizations related to system suspend and
     resume from Aaron Lu.

   - Cleanups related to ACPI video from Jean Delvare.

   - Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan
     Tianyu, Paul Bolle, Tomasz Nowicki.

   - Intel RAPL (Running Average Power Limits) driver cleanups from
     Jacob Pan.

   - intel_pstate fixes and cleanups from Dirk Brandewie.

   - cpufreq fixes related to system suspend/resume handling from Viresh
     Kumar.

   - cpufreq core fixes and cleanups from Viresh Kumar, Stratos
     Karafotis, Saravana Kannan, Rashika Kheria, Joe Perches.

   - cpufreq drivers updates from Viresh Kumar, Zhuoyu Zhang, Rob
     Herring.

   - cpuidle fixes related to the menu governor from Tuukka Tikkanen.

   - cpuidle fix related to coupled CPUs handling from Paul Burton.

   - Asynchronous execution of all device suspend and resume callbacks,
     except for ->prepare and ->complete, during system suspend and
     resume from Chuansheng Liu.

   - Delayed resuming of runtime-suspended devices during system suspend
     for the PCI bus type and ACPI PM domain.

   - New set of PM helper routines to allow device runtime PM callbacks
     to be used during system suspend and resume more easily from Ulf
     Hansson.

   - Assorted fixes and cleanups in the PM core from Geert Uytterhoeven,
     Prabhakar Lad, Philipp Zabel, Rashika Kheria, Sebastian Capella.

fc7392aa1b Input: don't modify the id of ioctl-provided ff effect on upload failure
If a new (id == -1) ff effect was uploaded from userspace,
ff-core.c::input_ff_upload() will have assigned a positive number to the
new effect id.  Currently, evdev.c::evdev_do_ioctl() will save this new id
to userspace, regardless of whether the upload succeeded or not.

On upload failure, this can be confusing because the dev->ff->effects[]
array will not contain an element at the index of that new effect id.

This patch fixes this by leaving the id unchanged after upload fails.

Note: Unfortunately applications should still expect changed effect id for
quite some time.

This has been discussed on:

421e08c41f Input: synaptics - add manual min/max quirk
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.

6797b39e6f Input: cypress_ps2 - don't report as a button pads
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:
