Move the second part of the HP laptop disk protection functionality (a red
led) to the same driver.  From a purely Linux developer's point of view,
the led and the accelerometer have nothing related.  However, they
correspond to the same ACPI functionality, and so will always be used
together, moreover as they share the same ACPI PNP alias, there is no
other simple to allow to have same loaded at the same time if they are not
in the same module.  Also make it requires the led class to compile and
update the Kconfig text.

The voltage and current regulators on the WM8350 AudioPlus PMIC can be
used in concert to provide a power efficient LED driver.  This driver
implements support for this within the standard LED class.

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.

NXP pca9532 is a LED dimmer/controller attached to i2c bus.  It allows
attaching upto 16 leds which can either be on, off or dimmed and/or blinked
with the two PWM modulators available.

This driver is a "new-style" i2c driver that adheres to the driver model and
implements the led framework api.  Since the leds connected to the driver are
platform specific, it is only useful when platform data is passed to the
driver to define what leds are connected to which pins.

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).

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.
