Sonic Zhang 71adf22f47 Input: bfin_rotary - use generic IO functions
Instead of using arch-specific accessors remap rotary register physical
address into kernel space in probe and use standard readw and writew to
access rotary MMRs.

Sonic Zhang 5ea0699a7b Input: bfin_rotary - move pin lists into into platform data
Newer Blackfin boards use pinctrl API to manage pins and the legacy
peripherial lists are not useful on them. Let's move pin lists into
platform data so older boards can still use them and newer boards can use
the modern API.

Dmitry Torokhov 5ec662e7a6 Input: bfin_rotary - mark suspend and resume code as __maybe_unused
Instead of using #ifdef to guard potentially unused suspend and resume code
let's mark them as __maybe_unused so they still get discarded if they are
not used but we do not get warning. This allows for better compile coverage.

Dmitry Torokhov 7694f44d63 Input: bfin_rotary - fix potential oops in interrupt handler
The interrupt handler in the driver tries to fetch driver data from
platform device, unfortunately it is only set up after interrupt handler
is registered. Since interrupt handler does not really need to access
the platform device itself let's change it to get the driver data
instance instead.

Bastien Nocera 791738be57 Input: soc_button_array - use "Windows" key for "Home"
KEY_HOME is the key to go back to the beginning of the line, not the key to
get into an overview mode, as Windows does. GNOME can already make use of
the Windows key on multiple form factors, and other desktop environments
can use it depending on the form factor.

Using "Windows" as the emitted key also means that the keycode sent out
matches the symbol on the key itself.

So switch KEY_HOME to KEY_LEFTMETA ("Windows" key).

Chang Huaixin 4d544e3bdb Input: xen-kbdfront - free grant table entry in xenkbd_disconnect_backend
xenkbd_disconnect_backend doesn't free grant table entry.  This bug affects
live migration.

xenkbd_disconnect_backend uses gnttab_end_foreign_access_ref to handle
grant table entry which doesn't really free an entry.

Thus every time we do xenkbd_resume, grant table entry increses by one. As
an grant table entry occupies 8 bytes, an grant table page has at most 512
entries. Every 512 times we do xenkdb_resume, grant table pages increses by
one.

After around 3500 times of live migration, grant table pages will increase
by 7, causing too many pages to populate and hitting max_pages limit when
assigning pages.Thus assign_pages will fail, so will live migration.

David Vrabel 95afae4814 xen: remove DEFINE_XENBUS_DRIVER() macro
The DEFINE_XENBUS_DRIVER() macro looks a bit weird and causes sparse
errors.

Replace the uses with standard structure definitions instead.  This is
similar to pci and usb device registration.

Jin Yao 042e1c7916 Input: soc_button_array - convert to platform bus
ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't
belong to PNP bus in nature.

Nishanth Menon adff5962fd Input: introduce palmas-pwrbutton
Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.

The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.

Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.

Sam Ravnborg d650471a39 sparcspkr: use sbus_*() primitives for IO
The memory are mapped using of_ioremap() which is
an indication this is sbus memory.
Shift all uses of inb/outb to the sbus variants.

The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L,
whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E.

The difference is if the reads/writes are done in
native or little endian.
But for byte reads/writes there is no difference
so this does not matter for inb/outb - and this
driver only uses the byte variants.

Linus Torvalds dfc25e4503 ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all
 be harmless. They are mainly split out so that other branches can
 be based on top to avoid conflicts.
 
 Notable changes are:
 
 * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
   longer used. (Uwe Kleine-König)
 * The Qualcomm MSM platform is split out into legacy mach-msm and
   new-style mach-qcom, to allow easier maintainance of the new
   hardware support without regressions. (Kumar Gala)
 * A rework of some of the Kconfig logic to simplify multiplatform
   support (Rob Herring)
 * Samsung Exynos gets closer to supporting multiplatform (Sachin
   Kamat and others)
 * mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
 * at91 gains some common clock framework support (Alexandre Belloni,
   Jean-Jacques Hiblot and other French people).

Currently, uinput does not provide the created input device, which means
that we rely on an heuristic to guess which input node was created.
The problem is that is heuristic is subjected to races between different
uinput devices or even with physical devices. Having a way to retrieve
the sysfs path allows us to find without any doubts the event node.

Sascha Hauer 557fe99d9d pwm: Remove obsolete HAVE_PWM Kconfig symbol
Before we had the PWM framework we used to have a barebone PWM api. The
HAVE_PWM Kconfig symbol used to be selected by the PWM drivers to specify
the PWM API is present in the kernel. Since the last legacy driver is gone
the HAVE_PWM symbol can go aswell.

- ACPI core changes to make it create a struct acpi_device object for every
    device represented in the ACPI tables during all namespace scans regardless
    of the current status of that device.  In accordance with this, ACPI hotplug
    operations will not delete those objects, unless the underlying ACPI tables
    go away.
 
  - On top of the above, new sysfs attribute for ACPI device objects allowing
    user space to check device status by triggering the execution of _STA for
    its ACPI object.  From Srinivas Pandruvada.
 
  - ACPI core hotplug changes reducing code duplication, integrating the
    PCI root hotplug with the core and reworking container hotplug.
 
  - ACPI core simplifications making it use ACPI_COMPANION() in the code
    "glueing" ACPI device objects to "physical" devices.
 
  - ACPICA update to upstream version 20131218.  This adds support for the
    DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

Pull Xen updates from Konrad Rzeszutek Wilk:
 "Two major features that Xen community is excited about:

  The first is event channel scalability by David Vrabel - we switch
  over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
  queue with priorities.  This lets us be able to handle more events,
  have lower latency, and better scalability.  Good stuff.

  The other is PVH by Mukesh Rathor.  In short, PV is a mode where the
  kernel lets the hypervisor program page-tables, segments, etc.  With
  EPT/NPT capabilities in current processors, the overhead of doing this
  in an HVM (Hardware Virtual Machine) container is much lower than the
  hypervisor doing it for us.

  In short we let a PV guest run without doing page-table, segment,
  syscall, etc updates through the hypervisor - instead it is all done
  within the guest container.  It is a "hybrid" PV - hence the 'PVH'
  name - a PV guest within an HVM container.

  The major benefits are less code to deal with - for example we only
  use one function from the the pv_mmu_ops (which has 39 function
  calls); faster performance for syscall (no context switches into the
  hypervisor); less traps on various operations; etc.

  It is still being baked - the ABI is not yet set in stone.  But it is
  pretty awesome and we are excited about it.

  Lastly, there are some changes to ARM code - you should get a simple
  conflict which has been resolved in #linux-next.

  In short, this pull has awesome features.

  Features:
   - FIFO event channels.  Key advantages: support for over 100,000
     events (2^17), 16 different event priorities, improved fairness in
     event latency through the use of FIFOs.
   - Xen PVH support.  "It’s a fully PV kernel mode, running with

to disable that they can set:

or

except it does not work properly. The PV drivers still try to
load and since the Xen platform driver is not run - and it

which is hardly nice. This patch fixes this by having each
PV driver check for:
 - if running in PV, then it is fine to execute (as that is their
   native environment).
 - if running in HVM, check if user wanted 'xen_emul_unplug=never',
   in which case bail out and don't load any PV drivers.
 - if running in HVM, and if PCI device 5853:0001 (xen_platform_pci)
   does not exist, then bail out and not load PV drivers.
 - (v2) if running in HVM, and if the user wanted 'xen_emul_unplug=ide-disks',
   then bail out for all PV devices _except_ the block one.
   Ditto for the network one ('nics').
 - (v2) if running in HVM, and if the user wanted 'xen_emul_unplug=unnecessary'
   then load block PV driver, and also setup the legacy IDE paths.
   In (v3) make it actually load PV drivers.

Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Merge tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO changes from Linus Walleij:
 "Here is the bulk of GPIO changes for the v3.13 development cycle.

  I've got ACKs for the things that affect other subsystems (or it's my
  own subsystem, like pinctrl).  Most of that pertain to an attempt from
  my side to consolidate and get rid of custom GPIO implementations in
  the ARM tree.  I will continue doing this.

  The main change this time is the new GPIO descriptor API, background
  for this can be found in Corbet's summary from this january in LWN:

    http://lwn.net/Articles/533632/

  Summary:

   - Merged the GPIO descriptor API from Alexandre Courbot.  This is a
     first step toward trying to get rid of the global GPIO numberspace
     for the future.

   - Add an API so that driver can flag that a certain GPIO line is
     being used by a irqchip backend for generating IRQs, so that we can
     enforce checks, like not allowing users to switch that line to an
     output at runtime, since this makes no sense.  Implemented
     corresponding calls in a few select drivers.

   - ACPI GPIO cleanups, refactorings and switch to using the
     descriptor-based interface.

   - Support for the TPS80036 Palmas GPIO variant.

   - A new driver for the Broadcom Kona GPIO SoC IP block.

   - Device tree support for the PCF857x driver.

   - A set of ARM GPIO refactorings with the goal of getting rid of a
     bunch of custom GPIO implementations from the arch/arm/* tree:

     * Move the IOP GPIO driver to the GPIO subsystem and fix all users
       to use the gpiolib API for accessing GPIOs.  Delete the old

Majunath Goudar 33777f34b5 Input: fix PWM-related undefined reference errors
This patch adds a PWM dependency to configure the INPUT_MAX8997_HAPTIC
and INPUT_PWM_BEEPER. Without this patch, build system can lead to build
failure. This was observed during randconfig testing, in which
INPUT_MAX8997_HAPTIC or INPUT_PWM_BEEPER was enabled w/o PWM being
enabled, leading to the following errors:

init/built-in.o
drivers/built-in.o: In function `max8997_haptic_disable':

Linus Walleij b22973d0ec input: misc: ixp4-beeper: use gpiolib strictly
Request and free the GPIO line used for the beeper properly.
Then use the gpiolib API to flip the output of the GPIO pin
instead of relying on hacks to poke the register bits.

Linus Walleij e9c9fc2315 input: misc: ixp4-beeper: switch to use gpiolib
The platform using this beeper has support for gpiolib, so there
is no point to use the custom gpio_line* API. A strange ambiguity
where a line was first set as input and then driven high was
solved by first driving the line high as output and then switch
it to input.

Andrey Moiseev 1ea4c16120 Input: add driver for slidebar on Lenovo IdeaPad laptops
This driver adds support for slidebars found on some Lenovo IdeaPad
laptops (the slidebars work with SlideNav/Desktop Navigator under
Windows).

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004

Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.

Now works on:
IdeaPad Y550, Y550P.

May work on (testing and adding new models is needed):
Ideapad Y560, Y460, Y450, Y650,
and, probably, some others.
