    [POWERPC] Souped-up of_platform_device support · 7eebde70
    Benjamin Herrenschmidt authored
    This patch first splits of_device.c and of_platform.c, the later containing
    the bits relative to of_platform_device's. On the "breaks" side of things,
    drivers uisng of_platform_device(s) need to include asm/of_platform.h now
    and of_(un)register_driver is now of_(un)register_platform_driver.
    
    In addition to a few utility functions to locate of_platform_device(s),
    the main new addition is of_platform_bus_probe() which allows the platform
    code to trigger an automatic creation of of_platform_devices for a whole
    tree of devices.
    
    The function acts based on the type of the various "parent" devices encountered
    from a provided root, using either a default known list of bus types that can be
    "probed" or a passed-in list. It will only register devices on busses matching
    that list, which mean that typically, it will not register PCI devices, as
    expected (since they will be picked up by the PCI layer).
    
    This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
    and can be used by any embedded-type device as well.
