    x86: geode: New PCEngines Alix system driver · d4f3e350
    Ed Wildgoose 提交于
    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: 7f131cf3 ("leds:
    leds-alix2c - take port address from MSR) by Daniel Mack to perform
    detection of the Alix board.
