TI LP8788 PMU supports regulators, battery charger, RTC, ADC, backlight
dri= ver and current sinks. This patch enables LP8788 backlight module.(Brightness mode)
The brightness is controlled by PWM input or I2C register.
All modes are supported in the driver.(Platform data)
Configurable data can be defined in the platform side.
name : backlight driver name. (default: "lcd-backlight")
initial_brightness : initial value of backlight brightness
bl_mode : brightness control by PWM or lp8788 register
dim_mode : dimming mode selection
full_scale : full scale current setting
rise_time : brightness ramp up step time
fall_time : brightness ramp down step time
pwm_pol : PWM polarity setting when bl_mode is PWM based
period_ns : platform specific PWM period value. unit is nano.The default values are set in case no platform data is defined.

Pull PWM changes from Thierry Reding:
"A new driver has been added to support the PWM mode of the timer
counter blocks found on Atmel AT91 SoCs. The VT8500 driver now
supports changing the PWM signal polarity and the TI drivers (EHRPWM
and ECAP) gained suspend and resume functionality.User drivers can now query the core for whether access to a PWM device
will sleep (if the PWM chip is on a slow bus such as I2C or SPI).The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK
state in addition to the FB layer's blanking states.To round things off, a few fixes and cleanups are also included"

LP8557 is one of LP855x family device, but it has different register map

At this moment, LP855x device driver has fixed register configuration.
For example, fixed register addresses and values are set on the device
initialization. But new device of LP855x family, LP8557 has different
register map and initialization sequence. To support new device
architecture, initialization process should be changed.Introduce new structure: lp855x_device_config
=============================================
With lp855x_device_config, device specific features are configurable.
Use configurable function calls and register addresses rather than fixed values.Change on device initialization
===============================
In old LP855x driver architecture, the device initialization was simple.
- Just update the brightness/device control register/ROM area(optional).
In new LP855x driver architecture, two more works are added - pre_init and
post_init.
Those init functions are optional, used for new device LP8557.New device initialization flow: generic sequence
=================================================
1) pre_init_device()
2) update the brightness register
3) update the device control register
4) update ROM area if need
5) post_init_device()Name change
===========
Use generic name 'lp855x_configure()' instead of 'lp855x_init_registers()'.Signed-off-by: Milo(Woogyom) Kim

This is an initial commit of a backlight driver, using step-up DCDC
power supplies on AS3711 PMIC. Only one mode has actually been tested,
several further modes have been implemented "dry," but disabled to avoid
accidental hardware damage. Anyone wishing to use any of those modes
will have to modify the driver.Tested on sh73a0-based kzm9g board. Only one mode has been tested and
is enabled. That mode copies the sample code from the manufacturer.
