    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.

    Prabhakar Lad, Philipp Zabel, Rashika Kheria, Sebastian Capella.

    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:
    http://www.mail-archive.com/linux-input@vger.kernel.org/msg08513.html

    18

    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.

  • 6797b39e6   Input: cypress_ps2 - don't report as a button pads ... Browse Code »

    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:
