This patch adds DT support to touch driver. It also provides a binding
document which is used by the MFD and IIO part of the device.
This patch also renames steps_to_configure to coordinate_readouts
because the original name misleads the purpose of the variable.

"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.

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.

Some matrix keypad drivers can support different numbers of rows and
columns. Add a generic binding for these.
Implementation note:
In order to implement this binding in the kernel, we will need to modify
matrix_keypad_() to look up the number of rows and cols in
the keymap. Perhaps this could be done by passing 0 for these parameters?
Many of the parameters can already be set to NULL. Ick.

This patch allows the STMPE driver to be successfully probed and

platform data changes, we also separate the process of filling in
the 'in use' pin bitmap, as we have to extract the information from
Device Tree in the DT boot case.
