    Input: add OLPC AP-SP driver · b56ece9a
    Daniel Drake authored
    The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
    keyboard, yet they do not have a hardware PS/2 controller. Instead, a
    firmware runs on a dedicated core ("Security Processor", part of the SoC)
    that acts as a PS/2 controller through bit-banging.
    
    Communication between the main cpu (Application Processor) and the
    Security Processor happens via a standard command mechanism implemented
    by the SoC. Add a driver for this interface to enable keyboard/mouse
    input on this platform.
