2007-01-05[PATCH] Fix leds-s3c24xx hardware.h referenceRichard Purdie
Russell King recently reminded us that one shouldn't use asm/arch/hardware.h but one should use asm/hardware.h (http://lkml.org/lkml/2006/12/23/26). Unfortunately, the leds-s3c24xx driver is using the wrong header. This patch is fixing that.

2006-12-07[PATCH] PCEngines WRAP LED SupportKristian Kielhofner
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.

2006-10-01[PATCH] leds: turn LED off when changing triggersPaul Collins
I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger.
