From: Ed Wildgoose Date: Tue, 20 Sep 2011 21:00:12 +0000 (-0700) Subject: x86: geode: New PCEngines Alix system driver X-Git-Tag: v3.2-rc1~142^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4f3e350172a1dc769ed5e7f5bd540feb0c475d8;p=pandora-kernel.git x86: geode: New PCEngines Alix system driver 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 as requested by Grant 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.
