-X-Git-Tag: next-20110812~1^2~75
-X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=2cd7b3e8f8078c214c93a2c60cb845500c92df4a;hp=dc849eae35bbf651ab3ee459f5683e1ff780413d
-
-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 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.
