78551277e4 Input: i8042 - add PNP modaliases
This allows the module to be autoloaded in the common case.

In order to work on non-PnP systems the module should be compiled in or
loaded unconditionally at boot (c.f. modules-load.d(5)), as before.

92eb77d0ff Input: evdev - fall back to vmalloc for client event buffer
evdev always tries to allocate the event buffer for clients using
kzalloc rather than vmalloc, presumably to avoid mapping overhead where
possible.  However, drivers like bcm5974, which claims support for
reporting 16 fingers simultaneously, can have an extraordinarily large
buffer.  The resultant contiguous order-4 allocation attempt fails due
to fragmentation, and the device is thus unusable until reboot.

Try kzalloc if we can to avoid the mapping overhead, but if that fails,
fall back to vzalloc.

5df682b297 Input: cypress_ps2 - do not consider data bad if palm is detected
If hardware (or firmware) detects palm on the surface of the device it does
not mean that the data packet is bad from the protocol standpoint. Instead
of reporting PSMOUSE_BAD_DATA in this case simply threat it as if nothing
touches the surface.

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:

We want to allow drivers to call input_event() at any time after the
device got allocated. This means input_event() and input_register_device()
must be allowed to run in parallel.

The only conflicting calls in input_register_device() are init_timer() and
dev_set_name(). Both can safely be moved to device allocation and we're
good to go.

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.

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.

baee539915 input: ti_am335x_tsc: Enable shared IRQ for TSC
Enable shared IRQ to allow ADC to share IRQ line from
parent MFD core. Only FIFO0 IRQs are for TSC and handled
on the TSC side.

Step mask would be updated from cached variable only previously.
In rare cases when both TSC and ADC are used, the cached
variable gets mixed up.
The step mask is written with the required mask every time.

Rachna Patil (TI) laid ground work for shared IRQ.

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).

Adds support for the sensors integrated in to the Cintiq Companion
Hybrid. These sensors use by-and-large the same protocol as the
Cintiq 24HD touch.

NOTE: The ExpressKeys on the Cintiq Companion Hybrid are wired to
both the EMR controller and CPU GPIO pins. It may be necessary 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).

Andrey Moiseev
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.
