Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux

2013-05-09T16:59:16+00:00

Pull removal of GENERIC_GPIO from Grant Likely:
 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

video: backlight: add ili922x lcd driver

2013-04-30T01:28:17+00:00

Add LCD driver for Ilitek ILI9221/ILI9222 controller.  The driver uses
SPI interface for controller access and configuration and RGB interface
for graphics data transfer.

drivers/video/backlight/Kconfig: fix typo "MACH_SAM9...EK" three times

2013-04-30T01:28:17+00:00

Fix three typos (originally) introduced by commit a9a84c37d1ee
("atmel_lcdfb: backlight control").

Two of these typos were introduced in v2.6.25.  (The third was
introduced in 915190f7d4f0 ("[ARM] 5614/1: at91: atmel_lcdfb: add
at91sam9g10 support to atmel LCD driver")).  Checking these commits
reveals that the default value of 'y' has never been set automatically
in all releases since v2.6.25! Perhaps this line might as well be
dropped.

Convert selectors of GENERIC_GPIO to GPIOLIB

2013-04-16T09:47:14+00:00

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

backlight: add new lp8788 backlight driver

2013-02-28T03:10:09+00:00

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.

backlight: lp855x_bl: support new LP8557 device

2013-02-22T01:22:25+00:00

LP8557 is one of LP855x family device, but it has different register map
and initialization process.  To support this device, device specific
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.

backlight: add an AS3711 PMIC backlight driver

2013-02-22T01:22:25+00:00

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...

backlight: ili9320: add missing SPI dependency

2012-10-25T21:37:52+00:00

Add this missing SPI dependency and prevent the driver from building
without SPI, because functions of the spi driver are used in this
driver.

  drivers/video/backlight/ili9320.c:51: undefined reference to `spi_sync'

Also, a prompt string for CONFIG_LCD_ILI9320 is added for explicit
selection.
