    ohci-platform: Change compatible string from usb-ohci to generic-ohci · ce149c30
    Hans de Goede authored
    The initial versions of the devicetree enablement patches for ohci-platform
    used "ohci-platform" as compatible string. However this was disliked by various
    reviewers because the platform bus is a Linux invention and devicetree is
    supposed to be OS agnostic. After much discussion I gave up and went with
    the generic usb-ohci as requested.
    
    In retro-spect I should have chosen something different, the dts files for many
    existing boards already claim to be compatible with "usb-ohci", ie they have:
    
    	compatible = "ti,ohci-omap3", "usb-ohci";
    
    In theory this should not be a problem since the "ti,ohci-omap3" entry takes
    presedence, but in practice using a conflicting compatible string is an issue,
    because it makes which driver gets used depend on driver registration order.
    
    This patch changes the compatible string claimed by ohci-platform to
    "generic-ohci", avoiding the driver registration / module loading ordering
    problems.
