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

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.

3ffdea3fec First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle
A number of new drivers and some new functionality + a lot of cleanups
 all over IIO.
 
 New Core Elements
 
 1) New INT_TIME info_mask element for integration time, which may have
    different effects on measurement noise and similar, than an amplifier
    and hence is different from existing SCALE.  Already existed in some
    drivers as a custom attribute.
 
 2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
    case of filling the last 64 bits of data to be passed to the buffer with
    a timestamp.  Applied to lots of drivers. Cuts down on repeated code and
    moves a slightly fiddly bit of logic into a single location.
 
 3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
    of elements such as sampling_frequency which is typically shared by all
    input channels on a device.  This reduces code and makes these controls
    available from in kernel consumers of IIO devices.
 
 New drivers
 
 1) MCP3422/3/4 ADC
 
 2) TSL4531 ambient light sensor
 
 3) TCS3472/5 color light sensor
 
 4) GP2AP020A00F ambient light / proximity sensor
 
 5) LPS001WP support added to ST pressure sensor driver.
 
 New driver functionality
 
 1) ti_am335x_adc Add buffered sampling support.
    This device has a hardware fifo that is fed directly into an IIO kfifo
    buffer based on a watershed interrupt.  Note this will act as an example
    of how to handle this increasingly common type of device.
    The only previous example - sca3000 - take a less than optimal approach
    which is largely why it is still in staging.
    A couple of little cleanups for that new functionality followed later.
 
 Core cleanups:
 
 1) MAINTAINERS - Sachin actually brought my email address up to date because
    I said I'd do it and never got around to it :)
 
 2) Assign buffer list elements as single element lists to simplify the
    iio_buffer_is_active logic.
 
 3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake
    up threads waiting for poll notifications.
 
 4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface.
 
 5) Change iio_push_to_buffers to take a void * pointer so as to avoid some
    annoying and unnecessary type casts.
 
 6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long.
 
 7) Various minor tidy ups.
 
 Driver cleanups (in no particular order)
 
 1) Another set of devm_ allocations patches from Sachin Kamat.
 
 2) tsl2x7x - 0 to NULL cleanup.
 
 3) hmc5843 - fix missing > in MODULE_AUTHOR
 
 4) Set of strict_strto* to kstrto* conversions.
 
 5) mxs-lradc - fix ordering of resource removal to match creation
 
 6) mxs-lradc - add MODULE_ALIAS
 
 7) adc7606 - drop a work pending test duplicated in core functions.
 
 8) hmc5843 - devm_ allocation patch
 
 9) Series of redundant breaks removed.
 
 10) ad2s1200 - pr_err -> dev_err
 
 11) adjd_s311 - use INT_TIME
 
 12)  ST sensors - large set of cleanups from Lee Jones and removed restriction
     to using only triggers provided by the st_sensors themselves from
     Dennis Ciocca.
 
 13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.
 
 14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
     suspend / resume functions.
 
 15) max1363 - use defaults for buffer setup ops as provided by the triggered
     buffer helpers as they are the same as were specified in max1363 driver.
 
 16) Trivial tidy ups in a number of other drivers.

4eb1830b49 Input: wacom - send proper tablet state info when pen leaves proximity
The EMR sensor of Intuos4 and newer devices can send a packet with
0x20 in its second byte which contains only location information.
This packet is sent when the pen is too far away to reliably obtain
other information. Because only the location is updated userspace
will continue to see stale information for other values, most notably
TOUCH, PRESSURE, and DISTANCE.

This patch ensures userspace is not left with stale device state
information when the pen re-enters proximity (possibly leading to
the assumption the pen is still in contact even though it is
actually hovering).

NOTE: The ExpressKeys on the Cintiq Companion Hybrid are wired to

disable their functionality in this driver if building a custom
Android kernel for this device (lest two events be sent to userspace
for every button press).

2f0d260413 Input: i8042 - i8042_flush fix for a full 8042 buffer
When 8042 internal data buffer is full, the driver
erroneously decides that the controller is not present.

i8042_flush returns the number of flushed bytes, which is
in 0 - I8042_BUFFER_SIZE range inclusive. Therefore, i8042_flush
has no way to indicate an error. Moreover i8042_controller_check
takes initially full buffer (i8042_flush returned
I8042_BUFFER_SIZE) as a sign of absence of the controller.

Let's change i8042 to return success/error instead and make sure
we do not return error prematurely.

dereferences it in all cases.  When device tree is used, a platform data
structure is allocated and initialized, and in all cases this pointer is copied
to the driver's private data, so the variable being tested should be accessed

David Herrmann
c7dc65737c Input: evdev - add EVIOCREVOKE ioctl
If we have multiple sessions on a system, we normally don't want
background sessions to read input events. Otherwise, it could capture
passwords and more entered by the user on the foreground session. This is
a real world problem as the recent XMir development showed:
  http://mjg59.dreamwidth.org/27327.html

We currently rely on sessions to release input devices when being
deactivated. This relies on trust across sessions. But that's not given on
usual systems. We therefore need a way to control which processes have
access to input devices.

With VTs the kernel simply routed them through the active /dev/ttyX. This
is not possible with evdev devices, though. Moreover, we want to avoid
routing input-devices through some dispatcher-daemon in userspace (which
would add some latency).

This patch introduces EVIOCREVOKE. If called on an evdev fd, this revokes
device-access irrecoverably for that *single* open-file. Hence, once you
call EVIOCREVOKE on any dup()ed fd, all fds for that open-file will be
rather useless now (but still valid compared to close()!). This allows us
to pass fds directly to session-processes from a trusted source. The
source keeps a dup()ed fd and revokes access once the session-process is
no longer active.
Compared to the EVIOCMUTE proposal, we can avoid the CAP_SYS_ADMIN
restriction now as there is no way to revive the fd again. Hence, a user
is free to call EVIOCREVOKE themself to kill the fd.

Additionally, this ioctl allows multi-layer access-control (again compared
to EVIOCMUTE which was limited to one layer via CAP_SYS_ADMIN). A middle
layer can simply request a new open-file from the layer above and pass it
to the layer below. Now each layer can call EVIOCREVOKE on the fds to
revoke access for all layers below, at the expense of one fd per layer.

There's already ongoing experimental user-space work which demonstrates
how it can be used:

the sequence of USB ids wrong. Reports from both Ian and Linus T show
that the 0x0291 id is for ISO, not ANSI, which should have the missing
number 0x0290. This patchs moves the three numbers accordingly, fixing

* Fix version recognition in elantech_set_properties

  The new hardware reports itself as v7 but the packets'
  structure is unaltered.

* Fix packet type recognition in elantech_packet_check_v4

  The bitmask used for v6 is too wide, only the last three bits of
  the third byte in a packet (packet[3] & 0x03) are actually used to
  distinguish between packet types.
  Starting from v7, additional information (to be interpreted) is
  stored in the remaining bits (packets[3] & 0x1c).
  In addition, the value stored in (packet[0] & 0x0c) is no longer
  a constant but contains additional information yet to be deciphered.
  This change should be backwards compatible with v6 hardware.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.

Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse

8c896308fe input: ti_am335x_adc: use only FIFO0 and clean up a little
The driver programs a threshold of "coordinate_readouts" say 5. The
REG_FIFO0THR registers says it should it be programmed to "threshold
minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2.
Multiplied by two because 5 for X and 5 for Y and plus 2 because we have
two Z.
The whole thing kind of works because It reads the 5 coordinates for X
and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored
within the loop and read later.
Nothing guaranties that FIFO1 is ready by the time it is read. In fact I
could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for
Y channel 7 for Z. The problem is that channel 7 and channel 12 got
somehow mixed up.
The other Problem is that FIFO1 is also used by the IIO part leading to
wrong results if both (tsc & adc) are used.

The patch tries to clean up the whole thing a little:
- Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter
  part in the for loop. This is just confusing.

- Use only FIFO0 in TSC. The fifo has space for 64 entries so should be
  fine.

- Read the whole FIFO in one function and check the channel.

- in case we dawdle around, make sure we only read a multiple of our
  coordinate set. On the second interrupt we will cleanup the remaining
  enties.

The mfd driver creates platform data for the child devices and it is the

The copy of the structure makes a common lock in this structure a little
less usefull. Therefore the platform data is not a pointer to the

483180281f Input: evdev - flush queues during EVIOCGKEY-like ioctls
If userspace requests current KEY-state, they very likely assume that no
such events are pending in the output queue of the evdev device.
Otherwise, they will parse events which they already handled via
EVIOCGKEY(). For XKB applications this can cause irreversible keyboard
states if a modifier is locked multiple times because a CTRL-DOWN event is
handled once via EVIOCGKEY() and once from the queue via read(), even
though it should handle it only once.

Therefore, lets do the only logical thing and flush the evdev queue
atomically during this ioctl. We only flush events that are affected by
the given ioctl.

This only affects boolean events like KEY, SND, SW and LED. ABS, REL and
others are not affected as duplicate events can be handled gracefully by
user-space.

Note: This actually breaks semantics of the evdev ABI. However,
investigations showed that userspace already expects the new semantics and
we end up fixing at least all XKB applications.
All applications that are aware of this race-condition mirror the KEY
state for each open-file and detect/drop duplicate events. Hence, they do
not care whether duplicates are posted or not and work fine with this fix.

Also note that we need proper locking to guarantee atomicity and avoid
dead-locks. event_lock must be locked before queue_lock (see input-core).
However, we can safely release event_lock while flushing the queue. This
allows the input-core to proceed with pending events and only stop if it
needs our queue_lock to post new events.
This should guarantee that we don't block event-dispatching for too long
while flushing a single event queue.

eeb065582a Input: synaptics - fix sync lost after resume on some laptops
In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.

After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.

There are two PS/2 commands in psmouse_probe():

  1. PSMOUSE_CMD_GETID
  2. PSMOUSE_CMD_RESET_DIS

Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times.  So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

d7ab7302f9 For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery and power
   management services. This controller is accessible through i2c or SPI.
 
 - Silicon Laboratories 476x controller, providing access to their FM chipset
   and their audio codec.
 
 - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader.
 
 - Nokia's Tahvo power button and watchdog device. This device is very similar
   to Retu and is thus supported by the same code base.
 
 - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by
   the stmpe driver.
 
 - ST-Ericsson AB8540 and AB8505 power management and voltage converter
   controllers through the existing ab8500 code.
 
 Some other drivers got cleaned up or improved. In particular:
 
 - The Linaro/STE guys got the ab8500 driver in sync with their internal code
   through a series of optimizations, fixes and improvements.
 
 - The AS3711 and OMAP USB drivers now have DT support.
 
 - The arizona clock and interrupt handling code got improved.
 
 - The wm5102 register patch and boot mechanism also got improved.

0c6a61657d Input: trackpoint - Optimize trackpoint init to use power-on reset
The trackpoint driver sets various parameter default values, all of
which happen to be power-on defaults (Source: IBM TrackPoint Engineering
Specification, Version 4.0. Also confirmed by empirical data).

By sending the power-on reset command to reset all parameters to
power-on state, we can skip the lengthy process of programming all
parameters. In testing, ~2.5 secs of time writing parameters was reduced
to .35 seconds waiting for power-on reset to complete.

4384041533 input: matrix-keymap: Add function to read the new DT binding
We now have a binding which adds two parameters to the matrix keypad DT
node. This is separate from the GPIO-driven matrix keypad binding, and
unfortunately incompatible, since that uses row-gpios/col-gpios for the
row and column counts.

So the easiest option here is to provide a function for non-GPIO drivers
to use to decode the binding.

Note: We could in fact create an entirely separate structure to hold
these two fields, but it does not seem worth it, yet. If we have more
parameters then we can add this, and then refactor each driver to hold
such a structure.

1c6ba37b3d arm-soc: bug fixes for 3.9-rc3
Things are calming down for arm-soc as well. This set of bug fixes is
 dominated in size by the at91 platform bug fixes. Some of them were
 meant to go through the framebuffer tree during the merge window, but
 since the framebuffer maintainer could not be reached, I offered to
 take them here. The other notable at91 change is the addition of pinctrl
 definitions to fix the NAND controller.
 
 The rest are mostly simple regression fixes:
 
 * Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
   renaming of the Kconfig symbol. You will get a trivial merge conflict
   here, we still want to remove it.
 * missing bits for clocks on imx and s5pv210
 * missing header inclusions in mmp and shmobile
 * typos in s5pv210 camera and vt8500 clock support code
 
 and three trivial fixes for pre-3.8 bugs:
 
 * an old bogus build warning in the joystick driver
 * a misleading Kconfig description
 * a NULL pointer check on davinci

devm_request_and_ioremap() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages; so all explicit
error messages can be removed from the failure code paths.

6fdd496e07 input/joystick: use get_cycles on ARM
ARM normally has an accurate clock source, so
we can theoretically use analog joysticks more
accurately and at the same time avoid the
build warning

 #warning Precise timer not defined for this architecture.

from the joystick driver.

Now, why anybody would use that driver no ARM I have no
idea, but Ben Dooks enabled it in the s3c2410_defconfig
along with a bunch of other drivers, even though that
platform has neither ISA nor PCI support. It still
seems to be the right thing to fix this quirk.

628329d524 Input: add IMS Passenger Control Unit driver
The PCU is a device installed in the armrest of a plane seat and
is connected to IMS Rave Entertainment System. It has a set of control
buttons (Volume Up/Down, Attendant, Lights, etc) on one side and
gamepad-like controls on the other side.

Originally the device was handled from userspace and because of that
it presents itself on USB bus as a CDC-ACM modem device that however
can not make calls. However the custom handling is not as convenient
as using standard input subsystem facilities. If it was pure input
device it would be possible to continue using userspace solution
(moving it over to uinput), but the device also has backlighted keys
which can not be supported via uinput.
