This change makes use of the devm_input_allocate_device() function, which
gets rid of the input_free_device() and input_unregister_device() calls.
When a device is allocated via input_allocate_device(), the
input_register_device() call will also be device-managed, so there is no
longer need to manually call unregister.
Also, the irq is allocated with the devm_request_threaded_irq(), so with
these two changes, the adp5589_keypad_remove() function is no longer
needed.
This cleans up the error & exit paths.

This adds the code for the Atmel touchscreens such as mXT224 to obtain
power regulators for the supply voltages AVDD and VDD. On mobile phones
such as Samsung GT-I8190 (Golden) this is needed to explicitly bring power
online.
We just enable the regulators at probe() and disable them at remove()
or in the error path for now.
As regulators are naturally stubbed if not available, this should have no
impact on existing systems.

This driver uses GPIO descriptors to drive the touchscreen RESET line. In
the existing device trees this has in conflict with intution been flagged
as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by
driving the line low (setting to 0) to enter reset state and driving the
line high (setting to 1) to get out of reset state.
The correct way to handle active low GPIO lines is to provide the
GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware)
and letting the GPIO framework invert the assertion (driving high) to a
low level and vice versa.
This is considered a bug since the device trees are incorrectly
mis-specifying the line as active high.
Fix the driver and all device trees specifying a reset line.

In some rare cases the 32 bit Rt value will overflow if z2 and x is max,
z1 is minimal value and x_plate_ohms is relatively high (for example 800
ohm). This would happen on some screen age with low pressure.
There are two possible fixes:
- make Rt 64bit
- reorder calculation to avoid overflow
The second variant seems to be preferable, since 64 bit calculation on
32 bit system is a bit more expensive.

When TOUCHSCREEN_ADC is enabled and IIO_BUFFER is disabled, it results
in the following Kbuild warning:
WARNING: unmet direct dependencies detected for IIO_BUFFER_CB
Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
Selected by [y]:
- TOUCHSCREEN_ADC [=y] && !UML && INPUT [=y] && INPUT_TOUCHSCREEN [=y] && IIO [=y]
The reason is that TOUCHSCREEN_ADC selects IIO_BUFFER_CB without depending
on or selecting IIO_BUFFER while IIO_BUFFER_CB depends on IIO_BUFFER. This
can also fail building the kernel.
Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.

We need to make sure we cancel the reinit work before we tear down the
driver structures.

The eKTF2132 is a touchscreen controller found, for example, in the Kobo
Aura ebook reader. It is similar to the ektf2127, but it uses a different
packet type to report touch events.

The i8042 module exports several symbols which may be used by other
modules.
Before this commit it would refuse to load (when built as a module itself)
on systems without an i8042 controller.
This is a problem specifically for the asus-nb-wmi module. Many Asus
laptops support the Asus WMI interface. Some of them have an i8042
controller and need to use i8042_install_filter() to filter some kbd
events. Other models do not have an i8042 controller (e.g. they use an
USB attached kbd).
Before this commit the asus-nb-wmi driver could not be loaded on Asus
models without an i8042 controller, when the i8042 code was built as
a module (as Arch Linux does) because the module_init function of the
i8042 module would fail with -ENODEV and thus the i8042_install_filter
symbol could not be loaded.
This commit fixes this by exiting from module_init with a return code
of 0 if no controller is found. It also adds a i8042_present bool to
make the module_exit function a no-op in this case and also adds a
check for i8042_present to the exported i8042_command function.
The latter i8042_present check should not really be necessary because
when builtin that function can already be used on systems without
an i8042 controller, but better safe then sorry.
