Could you also have a look at "[4/5] usb: host: xhci-plat:
Create platform device for onboard hubs in probe()"
(https://lore.kernel.org/patchwork/patch/1425453/)? It's a
relatively short patch that creates the platform device for
the driver from xhci-plat as you suggested in the v4
discussion.

I'm not the maintainer for xhci-related drivers.

However, there is at least one thing about this patch which looks 
suspicious: Adding the onboard_hub_dev pointer to struct usb_hcd instead 
of to struct xhci_plat_priv, where it would make a lot more sense.

I can move it to struct usb_hcd if that's preferred

Thinko: The patch already has it in struct usb_hcd.  I suggested moving 
it to struct xhci_plat_priv.

Ah, didn't actively recall to which struct I added it to, it has been a
while since I wrote that patch ;-) Agreed that struct xhci_plat_priv is
a better place.
