Merge branch 'akpm' (Andrew's patch-bomb)

2012-10-05T18:09:16+00:00

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."

backlight: remove ProGear driver

2012-10-05T18:04:53+00:00

This driver was for the ProGear webpad device which was produced in
2000/2001 and is not available on a market.  I no longer have this
hardware so can not even check how Linux works on it.

backlight: add new lm3639 backlight driver

2012-10-05T18:04:53+00:00

This driver is a general version for LM3639 backlgiht + flash driver chip
of TI.

LM3639:
The LM3639 is a single chip LCD Display Backlight driver + white LED
Camera driver.  Programming is done over an I2C compatible interface.

backlight: add Backlight driver for lm3630 chip

2012-10-05T18:04:53+00:00

This driver is a general version for LM3630 backlgiht driver chip of TI.

LM3630 :
The LM3630 is a current mode boost converter which supplies the power
and controls the current in two strings of up to 10 LEDs per string.
Programming is done over an I2C compatible interface.

backlight: Add TPS65217 WLED driver

2012-09-25T08:42:02+00:00

The TPS65217 chip contains a boost converter and current sinks which can be
used to drive LEDs for use as backlights. Expose this functionality via the
backlight API.

Tested on an AM335x based custom board with a single WLED string, using
different values for ISEL and FDIM (though it would be hard to tell the
difference except for the value in WLEDCTRL1). Both instantiation through the
device tree and by passing platform data have been tested. Testing has been
done with an Androidized 3.2 kernel from the rowboat project. Koen Kooi
reported the driver to be working on a Beaglebone board with LCD3 cape

backlight: add LM3533 backlight driver

2012-05-29T23:22:29+00:00

Add sub-driver for the backlights on National Semiconductor / TI LM3533
lighting power chips.

The chip provides 256 brightness levels and ambient-light-sensor and pwm
input control.

backlight: add driver for DA9052/53 PMIC v1

2012-04-05T22:25:51+00:00

DA9052/53 PMIC has capability to supply power for upto 3 banks of 6
white serial LEDS.  It can also control intensity of independent banks
and to drive these banks boost converter will provide up to 24V and
forward current of max 50mA.

This patch allows to control intensity of the individual WLEDs bank
through DA9052/53 PMIC.

This patch is functionally tested on Samsung SMDKV6410.

backlight: add support for Pandora backlight

2012-03-23T23:58:33+00:00

Add support for pandora (openpandora.org) backlight.

It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave.  Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm
nowadays.  The PMIC PWM driver is currently missing too, so pwm_bl.c
can't be used anyway.

backlight: new backlight driver for LP855x devices

2012-03-23T23:58:33+00:00

THis driver supports TI LP8550/LP8551/LP8552/LP8553/LP8556 backlight
devices.

The brightness can be controlled by the I2C or PWM input.  The lp855x
driver provides both modes.  For the PWM control, pwm-specific functions
can be defined in the platform data.  And some information can be read
via the sysfs(lp855x device attributes).

For details, please refer to Documentation/backlight/lp855x-driver.txt.
