The LEDS infrastructure itself does not require anything
that a platform dependant upon HAS_IOMEM.
The individual drivers do, but they are properly guarded
with the necessary platform dependencies.
One can even imagine a hypervisor based LED driver that
a platform without HAS_IOMEM might have.

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.

Add LED Class device support for the Soekris net48xx Error LED. Tested

a way of detecting a Soekris net48xx device but there is no DMI or any
Soekris-specific PCI devices.
