Magnus Damm f59b6f9f32 leds: Renesas TPU LED driver
Add V2 of the LED driver for a single timer channel for the TPU hardware
block commonly found in Renesas SoCs.

The driver has been written with optimal Power Management in mind, so to
save power the LED is driven as a regular GPIO pin in case of maximum
brightness and power off which allows the TPU hardware to be idle and
which in turn allows the clocks to be stopped and the power domain to be
turned off transparently.

Any other brightness level requires use of the TPU hardware in PWM mode.
TPU hardware device clocks and power are managed through Runtime PM.
System suspend and resume is known to be working - during suspend the LED
is set to off by the generic LED code.

The TPU hardware timer is equipeed with a 16-bit counter together with an
up-to-divide-by-64 prescaler which makes the hardware suitable for
brightness control.  Hardware blink is unsupported.

The LED PWM waveform has been verified with a Fluke 123 Scope meter on a
sh7372 Mackerel board.  Tested with experimental sh7372 A3SP power domain
patches.  Platform device bind/unbind tested ok.

V2 has been tested on the DS2 LED of the sh73a0-based AG5EVM.

Ed Wildgoose d4f3e35017 x86: geode: New PCEngines Alix system driver
This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs

Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also

This driver is inspired by leds-net5501.c by Alessandro Zummo.

Ideally, leds-net5501.c should also be moved to platform/geode. 
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.

Uwe Kleine-König 4440673a95 leds: provide helper to register "leds-gpio" devices
This function makes a deep copy of the platform data to allow it to live
in init memory.  For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.

As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.

Joachim Eastwood 3c1ab50d0a drivers/leds/leds-pca9532.c: add gpio capability
Allow unused leds on pca9532 to be used as gpio.  The board I am working
on now has no less than 6 pca9532 chips.  One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.

There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
 232         {       .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
 233         {       .type = PCA9532_TYPE_NONE }, /* reset gpio */

This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set.  The gpio will registers all chip
pins but will filter on gpio_request.

Johannes Berg 5ada28bf76 led-class: always implement blinking
Currently, blinking LEDs can be awkward because it is not guaranteed that
all LEDs implement blinking.  The trigger that wants it to blink then
needs to implement its own timer solution.

Rather than require that, add led_blink_set() API that triggers can use.
This function will attempt to use hw blinking, but if that fails
implements a timer for it.  To stop blinking again, brightness_set() also
needs to be wrapped into API that will stop the software blink.

As a result of this, the timer trigger becomes a very trivial one, and
hopefully we can finally see triggers using blinking as well because it's
always easy to use.

Antonio Ospite 5054d39e32 leds: LED driver for National Semiconductor LP3944 Funlight Chip
LEDs driver for National Semiconductor LP3944 Funlight Chip
http://www.national.com/pf/LP/LP3944.html

This helper chip can drive up to 8 leds, with two programmable DIM
modes; it could even be used as a gpio expander but this driver assumes
it is used as a led controller.

The DIM modes are used to set _blink_ patterns for leds, the pattern is
specified supplying two parameters:
  - period: from 0s to 1.6s
  - duty cycle: percentage of the period the led is on, from 0 to 100

LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
leds, the camera flash light and the displays backlights.

Kim Kyuwon 0b56129be7 leds: add BD2802GU LED driver
ROHM BD2802GU is a RGB LED controller attached to i2c bus and specifically
engineered for decoration purposes.  This RGB controller incorporates
lighting patterns and illuminates.

This driver is designed to minimize power consumption, so when there is no
emitting LED, it enters to reset state.  And because the BD2802GU has lots
of features that can't be covered by the current LED framework, it
provides Advanced Configuration Function(ADF) mode, so that user
applications can set registers of BD2802GU directly.

Here are basic usage examples :
; to turn on LED (not blink)
$ echo 1 > /sys/class/leds/led1_R/brightness
; to blink LED
$ echo timer > /sys/class/leds/led1_R/trigger
$ echo 1 > /sys/class/leds/led1_R/delay_on
$ echo 1 > /sys/class/leds/led1_R/delay_off
; to turn off LED
$ echo 0 > /sys/class/leds/led1_R/brightness

Felipe Balbi 17354bfe85 leds: Add gpio-led trigger
The gpio led trigger will allow leds to be triggered by
gpio events.

When we give the led a gpio number, the trigger will
request_irq() on that so we don't have to keep polling
for gpio state.

It's useful for usecases as n810's keypad leds that could
be triggered by the gpio event generated when user slides
up to show the keypad.

We also provide means for userland to tell us what is the
desired brightness for that special led when it goes on
so userland could use information from ambient light sensors
and not set led brightness too high if it's not necessary.

Trent Piepho a7d878af94 leds: Add openfirmware platform device support
Add bindings to support LEDs defined as of_platform devices in addition to
the existing bindings for platform devices.

New options in Kconfig allow the platform binding code and/or the
of_platform code to be turned on.  The of_platform code is of course only
available on archs that have OF support.

The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led.  The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.

The suspend and resume methods aren't shared, but they are very short.  The
actual led driving code is the same for LEDs created by either binding.

The OF bindings are based on patch by Anton Vorontsov
<avorontsov@ru.mvista.com>.  They have been extended to allow multiple LEDs
per device.

Platform initialisation code should configure the LED hardware in the
init callback provided by the WM8350 core driver.  The callback should
use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and
wm8350_dcdc_set_slot() to configure the operating parameters of the
regulators for their hardware and then then use wm8350_register_led() to
instantiate the LED driver.

This driver was originally written by Liam Girdwood, though it has been
extensively modified since then.

David Brownell de5c9edee7 PWM LED driver
This is a LED driver using the PWM on newer SOCs from Atmel; brightness is
controlled by changing the PWM duty cycle.  So for example if you've set up
two leds labeled "pwm0" and "pwm1":

	echo 0 > /sys/class/leds/pwm2/brightness	# off (0%)
	echo 80 > /sys/class/leds/pwm2/brightness
	echo 255 > /sys/class/leds/pwm2/brightness	# on (100%)

Note that "brightness" here isn't linear; maybe that should change.  Going
from 4 to 8 probably doubles perceived brightness, while 244 to 248 is
imperceptible.

This is mostly intended to be a simple example of PWM, although it's
realistic since LCD backlights are often driven with PWM to conserve
battery power (and offer brightness options).

Adrian Bunk 247537b9a2 kconfig: syntax cleanup - drop support for "depends/requires/def_boolean"
Remove the following redundant and never or rarely used kconfig syntax:

- "def_boolean" (same as "def_bool")
- "requires" (same as "depends on")
- "depends" (same as "depends on")

This patch contains the code changes and Kconfig updates.
The shipped files are in next patch to let actual codechange stand out.

Kristian Kielhofner 0d75565f1e [PATCH] PCEngines WRAP LED Support
A driver for the PCEngines WRAP boards (http://www.pcengines.ch), which are
very similar to the Soekris net4801 (same NS SC1100 geode reference
design).

The LEDs on the WRAP are on different GPIO lines and I have modified and
copied the net48xx error led support for this.  It also includes support
for an "extra" led (in addition to error).  The three LEDs on the WRAP are
at GPIO lines 2,3,18 (WRAP LEDs from left to right).  This driver gives
access to the second and third LEDs by twiddling GPIO lines 3 & 18.

Because these boards are so similar to the net48xx, I basically sed-ed that
driver to form the basis for leds-wrap.c.  The only changes from
leds-net48xx.c are:

 - #define WRAP_EXTRA_LED_GPIO

 - name changes

 - duplicate relevant sections to provide support for the "extra" led

 - reverse the various *_led_set values.  The WRAP is "backwards" from the
   net48xx, and these needed to be updated for that.

Chris Boot 1a87d9425e [PATCH] LED Class support for Soekris net48xx
Add LED Class device support for the Soekris net48xx Error LED.  Tested
only on a net4801, but should work on a net4826 as well.  I'd love to find
a way of detecting a Soekris net48xx device but there is no DMI or any
Soekris-specific PCI devices.
