Dmitry Torokhov 5383116b86 Input: marix-keymap - automatically allocate memory for keymap
In device tree enabled setups requiring preallocated memory for storing keymap
is quite often awkward, so let's provide an option of allocating it directly
in matrix_keypad_build_keymap().

Dmitry Torokhov 2be975c6d9 Input: introduce managed input devices (add devres support)
There is a demand from driver's writers to use managed devices framework
for their drivers. Unfortunately up to this moment input devices did not
provide support for managed devices and that lead to mixing two styles
of resource management which usually introduced more bugs, such as
manually unregistering input device but relying in devres to free
interrupt handler which (unless device is properly shut off) can cause
ISR to reference already freed memory.

This change introduces devm_input_allocate_device() that will allocate
managed instance of input device so that driver writers who prefer
using devm_* framework do not have to mix 2 styles.

There are 16 programmable Step Configuration
registers which are used by the sequencer.
Program the Steps in order to configure a channel
input to be sampled. If the same step is applied
several times, the coordinate values read are more
accurate.
Hence we provide the user an option of how many steps
should be configured.

For ex: If this value is assigned as 4, This means that
4 steps are applied to read x co-ordinate and 4 steps to read
y co-ordinate. Furtheron the interrupt handler already
holds code to use delta filter and report the best value
out of these values to the input sub-system.

Patil, Rachna 33f5cc605d input: TSC: ti_tscadc: Correct register usage
This patch cleans up the wrong register definitions
and usage for touchscreen controller.
Bit masks were not defined earlier.

For ex: consider a register define as:
write(xyz, ABC)
ABC is expected to be written to register bits 0-11.
Here we see that value written is as expected, but this write
is also affecting all the remaining bits of xyz.
The remaining bits hold the default value as 0 and the write
also sets it to zero. Hence wrong usage were not causing user
visible bugs.
Due to these reasons it was difficult to follow when
compared with TRM.

Unused definitions are also removed.
Since there is change in some naming convention because of
all the above mentioned reasons, the same has been
updated throughout the code.
Bit declarations are grouped to increase readability.

Linus Walleij 694e33a7f4 ARM: plat-nomadik: move MTU, kill plat-nomadik
This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.

As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.

After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

Jason Gerecke aea2bf6a57 Input: wacom - handle split-sensor devices with internal hubs
Like our other pen-and-touch products, the Cintiq 24HD touch needs data
to be shared between its two sensors to facilitate proximity-based palm
rejection.

Unlike other tablets that report sensor data through separate interfaces
of the same USB device, the Cintiq 24HD touch has separate USB devices
that are connected to an internal USB hub.

This patch makes it possible to designate the USB VID/PID of the other
device so that the two may share data.  To ensure we don't accidentally
link to a sensor from a physically separate device (if several have been
plugged in), we limit the search to siblings (i.e., devices directly
connected to the same hub).

Hui Wang ae495e844a Input: egalax_ts - get gpio from devicetree
The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework
and don't support this API anymore.

The i.MX6q sabrelite platform equips an egalax touchscreen controller,
and this platform already transfered to GENERIC_GPIO framework, to
support this driver, we use a more generic way to get gpio.

Add a return value checking for waking up the controller in the probe
function, this guarantee only a workable device can pass init.

Javier Martin a6e8c0a253 Input: qt2160 - fix qt2160_write() implementation
The previous implementation of qt2160_write() didn't work properly because
the value was actually not written to the device. Probably nobody detected
this because the only write that was issued was the one related to auto
calibration.

In order to fix the problem use a similar aproach as qt1070 instead.

Commit 7f8d4cad1e ("Input: extend the number of event (and other)
devices") made evdev, joydev and mousedev to embed struct cdev into
their respective structures representing input devices.

Unfortunately character device structure may outlive the parent
structure unless we do not set it up as parent of character device so
that it will stay pinned until character device is freed.

Also, now that parent structure is pinned while character device exists
we do not need to pin and unpin it every time user opens or closes it.

Extend the amount of character devices, such as eventX, mouseX and jsX,

all handlers.

To be compatible with legacy installations input handlers will start
creating char devices with minors in their legacy range, however once
legacy range is exhausted they will start allocating minors from the
dynamic range 256-1024.

This patch introduces the function wacom_fix_phy_from_hid to let
us make use of the unit and exponent data provided by HID to set
the [xy]_phy variables to an appropriate value. This function
relies on a trimmed-down version of hidinput_calc_abs_res from

The ability to set the proximity flag should apply to any device
that has both pen and touch input. Rather than listing classes of
devices known to meet this criteria, simply filter on the quirk
defining all such devices.

Jason Gerecke 4e90495498 Input: wacom - report correct touch contact size for I5/Bamboo
This changes how the touch packets for Intuos5 and 3rd-gen Bamboo
are interpreted, so that proper values for the MAJOR and MINOR
axes are reported. Instead of using the amplitude field (data[6]),
we use the size field (data[5]) and do some calculation to
transform it from a scaled-down area into axis lengths.

Note that even though we assume a circular contact, both MAJOR and
MINOR are reported since the resolution of the X and Y axes differ.

Linus Torvalds 033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

Linus Torvalds 9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

If the ExpressKeys on the Intuos5 are touched, they currently result
an out-of-prox packet being sent even if the pad is already out of
prox. This can cause some confusion in the X driver. To restore the
expected semantics, we make being touched a sufficient condition to
signal proximity.

Seth Forshee 824efd3741 Input: synaptics - adjust threshold for treating position values as negative
Commit c039450 (Input: synaptics - handle out of bounds values from the
hardware) caused any hardware reported values over 7167 to be treated as
a wrapped-around negative value. It turns out that some firmware uses
the value 8176 to indicate a finger near the edge of the touchpad whose
actual position cannot be determined. This value now gets treated as
negative, which can cause pointer jumps and broken edge scrolling on
these machines.

I only know of one touchpad which reports negative values, and this
hardware never reports any value lower than -8 (i.e. 8184). Moving the
threshold for treating a value as negative up to 8176 should work fine
then for any hardware we currently know about, and since we're dealing
with unspecified behavior it's probably the best we can do. The special
8176 value is also likely to result in sudden jumps in position, so
let's also clamp this to the maximum specified value for the axis.

Henrik Rydberg 51c80b7400 Input: bcm5974 - Convert to MT-B
Use of the in-kernel tracking code to convert the driver to MT-B.

With ten fingers on the pad, the in-kernel tracking adds approximately
25 us to the maximum irqsoff latency. Under normal workloads, however,
the tracking has no measurable effect.

Henrik Rydberg 0e7269669d Input: bcm5974 - Drop the logical dimensions
The logical scale is used to produce special finger width values to
userspace, but has become an unnecessary restriction for everything
else.  Also, the bcm5974 trackpads are very accurate and work well
without hysteresis.

This patch simplifies the driver and device data by removing the
logical scale, and by moving the special synaptics code out of the
main path.  Also add the orientation range, needed in a subsequent
patch, to the device configuration.

Henrik Rydberg 43f482b48d Input: bcm5974 - only setup button urb for TYPE1 devices
The early generations with this trackpad used the separate mouse
interface to produce button events. With the introduction of the
button pads, this information was moved to the trackpad interface,
leaving the mouse interface unused. The driver is still setting up
both interfaces, which has not caused any problems - until now.

It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the
driver may return an ENOSPC upon bt_urb submission, resulting in a
failure to open the device. This happens everytime on the MacBookPro
Retina (and likely on other mid-2012 models), but earlier MacBook
models seem to work fine.

This patch skips the bt_urb setup for TYPE2 devices, which arguably
should have been done in the first place.

Most MT drivers perform the same actions on frame synchronization.
Some actions, like dropping unseen contacts, are also unnecessarily
complex. Collect common frame synchronization tasks in a new function,
input_mt_sync_frame(). Depending on the flags set, it drops unseen
contacts and performs pointer emulation.

With init flags and frame synchronization in place, most MT drivers
can be simplified. First out are the bcm5974 and hid-multitouch
drivers, following this patch.

Henrik Rydberg 4369c64c79 Input: Send events one packet at a time
On heavy event loads, such as a multitouch driver, the irqsoff latency
can be as high as 250 us.  By accumulating a frame worth of data
before passing it on, the latency can be dramatically reduced.  As a
side effect, the special EV_SYN handling can be removed, since the
frame is now atomic.

This patch adds the events() handler callback and uses it if it
exists. The latency is improved by 50 us even without the callback.

The events-per-packet estimate has so far been used by MT devices
only. This patch adjusts the packet buffer size to also accomodate the
KEY and MSC events.  Keyboards normally send one or two keys at a
time. MT devices normally send a number of button keys along with the
MT information.  The buffer size chosen here covers those cases, and
matches the default buffer size in evdev. Since the input estimate is
now preferred, remove the special input-mt estimate.

This reverts commit ca3b3faf9b.

There was a plan to place ab8500_irq_get_virq() calls in each AB8500
child device prior to requesting an IRQ, but as we're no longer using
Device Tree to collect our IRQ numbers, it's actually better to allow
the core to do this during device registration time. So the IRQ number
we pull from its resource has already been converted to a virtual IRQ.

Forest Bond 037a833ed0 Input: usbtouchscreen - initialize eGalax devices
Certain eGalax devices expose an interface with class HID and protocol
None.  Some work with usbhid and some work with usbtouchscreen, but
there is no easy way to differentiate.  Sending an eGalax diagnostic
packet seems to kick them all into using the right protocol for
usbtouchscreen, so we can continue to bind them all there (as opposed to
handing some off to usbhid).

This fixes a regression for devices that were claimed by (and worked
with) usbhid prior to commit 139ebe8dc8
("Input: usbtouchscreen - fix eGalax HID ignoring"), which made
usbtouchscreen claim them instead.  With this patch they will still be
claimed by usbtouchscreen, but they will actually report events
usbtouchscreen can understand.  Note that these devices will be limited
to the usbtouchscreen feature set so e.g. dual touch features are not
supported.

I have the distinct pleasure of needing to support devices of both types
and have tested accordingly.

Dmitry Torokhov 22ae19c6e3 Input: uinput - fix race that can block nonblocking read
Consider two threads calling read() on the same uinput-fd, both
non-blocking. Assume there is data-available so both will simultaneously
pass:
	udev->head == udev->tail

Then the first thread goes to sleep and the second one pops the message
from the queue. Now assume udev->head == udev->tail. If the first thread
wakes up it will call wait_event_*() and sleep in the waitq. This
effectively turns the non-blocking FD into a blocking one.

We fix this by attempting to fetch events from the queue first and only
if we fail to retrieve any events we either return -EAGAIN (in case of
non-blocing read) or wait until there are more events.

This also fixes incorrect return code (we were returning 0 instead of
 -EAGAIN for non-blocking reads) when an event is "stolen" by another
thread. Blocking reads will now continue to wait instead of returning 0
in this scenario.

Count of 0 continues to be a special case, as per spec: we will check for
device existence and whether there are events in the queue, but no events
will be actually retrieved.

In order to avoid races with suspend, a wakeup event must register as
such by calling pm_wakeup_event() or pm_stay_awake().  This will ensure
that the current suspend cycle aborts.

When the user-space visible event is created in the interrupt handler
(gpio_keys_irq_isr), a simple pm_wakeup_event() with no delay is
sufficient as suspend will synchronise with all interrupt delivery.

When the user-space visible event is created later
(gpio_keys_gpio_isr), we need to bracket the event with
pm_stay_awake() and pm_relax().

not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.

Arnd Bergmann 4eef6cbfcc Input: eeti_ts: pass gpio value instead of IRQ
The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.

In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.

As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.

Without this patch, building raumfeld_defconfig results in:

drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

Seth Forshee c0394506e6 Input: synaptics - handle out of bounds values from the hardware
The touchpad on the Acer Aspire One D250 will report out of range values
in the extreme lower portion of the touchpad. These appear as abrupt
changes in the values reported by the hardware from very low values to
very high values, which can cause unexpected vertical jumps in the
position of the mouse pointer.

What seems to be happening is that the value is wrapping to a two's
compliment negative value of higher resolution than the 13-bit value
reported by the hardware, with the high-order bits being truncated. This
patch adds handling for these values by converting them to the
appropriate negative values.

The only tricky part about this is deciding when to treat a number as
negative. It stands to reason that if out of range values can be
reported on the low end then it could also happen on the high end, so
not all out of range values should be treated as negative. The approach
taken here is to split the difference between the maximum legitimate
value for the axis and the maximum possible value that the hardware can
report, treating values greater than this number as negative and all
other values as positive. This can be tweaked later if hardware is found
that operates outside of these parameters.

Lee Jones ca3b3faf9b input: ab8500-ponkey: Create AB8500 domain IRQ mapping
Before we can use any domain allocated IRQ, we need to first create a
map between the Hardware IRQ (hwirq) and the Linux Virtual IRQ (virq).
We do this with a helper function provided by the AB8500 IRQ domain
controller called ab8500_irq_get_virq(). We need to do this for both
IRQs which the Power-On-Key driver uses; one for button press, the other
for button depress.

On some platform it may happen that the input clock to keyboard may
change during suspend, thus impacting its wakeup capability.

There is no means for keyboard driver to know this frequency before
hand. Hence introduce a platform data 'suspended_rate' which indicates
the frequency during suspend at which keyboard operates.

Accordingly reprogram keyboard while going into suspend and restore
original configuration at the time of resume.

Shiraz Hashim 53fe628558 Input: spear_keyboard - fix clock handling during suspend/resume
SPEAr keyboard should normally disable clock during suspend and enable it
during resume.

For cases where it is expected to act as a wakeup source the clock can
remain in the same state i.e. kept enabled if it is being used.

Russell King 3169663ac5 ARM: sa11x0/pxa: convert OS timer registers to IOMEM
Make the OS timer registers have IOMEM like properities so they can
be passed to readl_relaxed/writel_relaxed() et.al. rather than being
straight volatile dereferences.  Add linux/io.h includes where
required.

linux/io.h includes added to arch/arm/mach-sa1100/cpu-sa1100.c,
 arch/arm/mach-sa1100/jornada720_ssp.c, arch/arm/mach-sa1100/leds-lart.c
 drivers/input/touchscreen/jornada720_ts.c, drivers/pcmcia/sa1100_shannon.c
from Arnd.

This fixes these warnings:

arch/arm/mach-sa1100/time.c:104: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type

Dan Carpenter 9a932145f2 Input: ff-memless - fix a couple min_t() casts
envelope->attack_level is a u16 type.  We're trying to clamp it here
so it's between 0 and 0x7fff.  Unfortunately, the cast to __s16 turns
all the values larger than 0x7fff into negative numbers and min_t()
thinks they are less than 0x7fff.  envelope_level is an int so now
we've got negative values stored there.
