The leds-cobalt driver only supports the Coable Qube series
(not included in Cobalt Raq series).

This patch adds support for GPIO connected leds via the new GPIO framework.

Information about leds (gpio, polarity, name, default trigger) is passed
to the driver via platform_data.

This patch adds the support for the IPAQ h1940 leds.

In order to create the amber led (used for the battery charging), the red and
green leds are set to the same default trigger. Due to hardware limitations,
the blue led can only be set in blinking mode.

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.

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.

Add support for LED triggers to the LED subsystem.  "Triggers" are events
which change the state of an LED.  Two kinds of trigger are available, simple
ones which can be added to exising code with minimum disruption and complex
ones for implementing new or more complex functionality.
