I can live with generic as pre/post fix. Looking at what seems to
be the common trend I believe it should be a pre-fix and nost a post-fix
though.

The common way to build a compatible string seems to be:
vendor,soc_model-function. We have a few deviations from this in the
usb bindings, but ie the interrupt-controller bindings use this
structure for the compatible strings everywhere.

So since generic has no vendor, we fill just the soc_model-function
part leading to:
generic-ohci
generic-ehci

And possible also:
generic-uhci
generic-xhci

So I'm going to respin my 2 fixup patches to move from ?hci-platform
to generic-?hci.

Regards,

Hans
