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.
