Jingoo Han 334a41ce9b mfd: Use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

Bill Pemberton 4740f73fe5 mfd: remove use of __devexit
CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

Milo Kim eea6b7cc53 mfd: Add lp8788 mfd driver
TI LP8788 PMU provides regulators, battery charger, ADC,
RTC, backlight driver and current sinks.

This MFD patch supports the I2C communication using the regmap,
the interrupt handling using the linear IRQ domain and
configurable platform data structures for each driver module.

 (Driver Architecture)

                                         < mfd devices >
  LP8788 HW  ..........  mfd  .......... regulator drivers
                I2C                      power supply driver
                IRQs                     iio adc driver
                                         rtc driver
                                         backlight driver
                                         current sink drivers

  o regulators    : LDOs and BUCKs
  o power supply  : Battery charger
  o iio adc       : Battery voltage/temperature
  o rtc           : RTC and alarm
  o backlight
  o current sink  : LED and vibrator

All MFD device modules are registered by LP8788 MFD core driver.
For sharing information such like the virtual IRQ number,
MFD core driver uses the resource structure.
Then each module can retrieve the specific IRQ number and detect it
in the IRQ thread.

Configurable platform data is handled in each driver module.
