With fast movements, there occured some out of screen jumps with my
touchscreen. The abs_x and abs_y module parameters should fix this by
default, but the driver doesn't actively checks the x/y coordinates.
Instead it seems that the input layer was supposed to drop out of range
inputs, as described in the comments:
"These parameters are used to help the input layer discard out of
range readings and reduce jitter etc"
The input layer documentation describes that values that are not in the
absolute range are also accepted.
So this patch adds a check within the driver.

When it uses regulators the mms114 driver checks to see if it managed to
acquire regulators and ignores errors. This is not the intended usage and
not great style in general.
Since the driver already refuses to probe if it fails to allocate the
regulators simply make the enable and disable calls unconditional and
add appropriate error handling, including adding cleanup of the
regulators if setup_reg() fails.

There is a more complete atmel patch-series out by Nick Dyer that fixes
this and other things, but in the meantime this is the minimal thing to
get the touchscreen going on (at least my) Pixel Chromebook.
Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a
constant wakeup source, so you have to disable it to go to sleep. And
it's easier to just fix the initialization sequence.

This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.
This will cause the driver to perform some touchpad specific
initializations, such as:
* register input device name "Atmel maXTouch Touchpad" instead of
Touchscreen.
* register BTN_LEFT & BTN_TOOL_* event types.
* register axis resolution (as a fixed constant, for now)
* register BUTTONPAD property
* process GPIO buttons using reportid T19
Input event GPIO mapping is done by the platform data key_map array.
key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.

Add the necessary code to create the needed platformdata from devicetree
informations.
The interrupt mode of the chip is not set via devicetree, as it is not
a property of the hardware but instead only a preferred type of operation.
This should probably be made settable via configfs in the future.
The option set as default is the mode the datasheet mentions as default.

Devicetree based platforms don't handle device callbacks very well
and until now no board has come along that needs more extended hwinit
than pulling the rst gpio high.
Therefore pull the reset handling directly into the driver and remove
the callbacks from the driver.

would probably be the solution of choice.

The touchscreen IP uses level sensitive interrupts rather
than edge sensitive interrupts and therefore the is no need
to use the EOI register to have the module re-strobe the
interrupt line if there pending interrupts exist.

Code currently uses FIFO1 threshold interrupt.
since this is a MFD, Dedicating FIFO0 to touchscreen
and making way for other devices to use FIFO1 as well.
The FIFO can be shared between 2 devices but since the
interrupt used is threshold interrupt on FIFO1, we would
end up having wrong interrupts. Hence changing the same.

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.

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.

The tsc40 driver announces it supports the pressure event, but will never
send one. The announcement will cause tslib to wait for such events and
sending all touch events with a pressure of 0. Removing the announcement
will make tslib fall back to emulating the pressure on touch events so
everything works as expected.

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.

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.

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

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.

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.

flush[_delayed]_work_sync() are now spurious. Mark them deprecated
and convert all users to flush[_delayed]_work().
If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
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.
This patch doesn't make any functional difference.

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]

Make the OS timer registers have IOMEM like properities so they can

Dmitry: I understand that I am a bit late to the party :) but I do not
agree with this change. Failure to create attributes is not sometihng
that user could cause (at least not easily) and thus would not be a
setup issue but something more severe. I believe we should fail
loading the driver so sysfs attribute breakage will be noticed as soon
as possible, instead of discovering it much much later in the process.
This reverts commit 6399003800.

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.
