The egalax_ts touchscreen modul not report ABS_MT_POSITION_Y proper.
As result it may be, that upper software levels only receive x coordinates well.

Pull removal of GENERIC_GPIO from Grant Likely:
"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."

Pull MFD update from Samuel Ortiz:
"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."

Use the key-matrix layer to interpret key scan information from the EC
and inject input based on the FDT-supplied key map. This driver registers
itself with the ChromeOS EC driver to perform communications.
The matrix-keypad FDT binding is used with a small addition to control
ghosting.

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.

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.

This patch converts the drivers to use the
module_platform_driver_probe() macro which makes the code smaller and
a bit simpler.

Use the newly introduced devm_ioremap_resource() instead of
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.

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.

Often a reading can be wrong. This patch assures that this is really a
pen up event and not a false reading.

Instead of interpreting a wrong measurement as pen up, we should
try to read again.

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.
