a38884f681 videomode: simplify videomode Kconfig and Makefile
This patch simplifies videomode related Kconfig and Makefile. After this
patch, there's only one non-user selectable Kconfig option left,
VIDEOMODE_HELPERS. The reasons for the change:

* Videomode helper functions are not something that should be shown in
  the kernel configuration options. The related code should just be
  included if it's needed, i.e. selected by drivers using videomode.

* There's no need to have separate Kconfig options for videomode and
  display_timing. First of all, the amount of code for both is quite
  small. Second, videomode depends on display_timing, and display_timing
  in itself is not really useful, so both would be included in any case.

* CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS
  describes better what's included.

c5a51053cf backlight: add new lp8788 backlight driver
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.

f7a3c997af drivers/video/backlight/ams369fg06.c: make power_on() call optional
This patch makes power_on() call optional.  The voltage source can be
provided to some boards using ams369fg06 panel, thus in this case, power
on/off sequence is not necessary.

3eb05225ee pwm: Changes for v3.9-rc1
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.

Getting the brightness value is not critical, no need to read the actual

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

configuration is done through the lp855x_device_config structure.

Few register definitions are fixed for better readability.
  BRIGHTNESS_CTRL -> LP855X_BRIGHTNESS_CTRL
  DEVICE_CTRL     -> LP855X_DEVICE_CTRL
  EEPROM_START    -> LP855X_EEPROM_START
  EEPROM_END      -> LP855X_EEPROM_END
  EPROM_START     -> LP8556_EPROM_START
  EPROM_END       -> LP8556_EPROM_END

And LP8557 register definitions are added.  New register function,
lp855x_update_bit() is added.

68853bc2b3 backlight: lp855x_bl: introduce device configuration flow
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()'.

5eb02c01bd drivers/video/backlight/adp88?0_bl.c: fix resume
Clearing the NSTBY bit in the control register also automatically clears
the BLEN bit.  So we need to make sure to set it again during resume,
otherwise the backlight will stay off.

gamma_table has 3 arrays which each hold MAX_GAMMA_LEVEL pointers to int.

The current code sets ->gamma_table_count to 6 on 64bit arches and to 3 on
32 bit arches.  It should be 3 on everything.

c84c383366 drivers/video/backlight/88pm860x_bl.c: add missing of_node_put()
of_find_node_by_name() returns a node pointer with refcount incremented,
use of_node_put() on it when done.

of_find_node_by_name() will call of_node_put() against the node pass to
from parameter, thus we also need to call of_node_get(from) before calling
of_find_node_by_name().

de474b5bfc backlight: add an AS3711 PMIC backlight driver
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.
Deviations from that code proved to be fatal for the hardware...
