Let's look v2 patch, it bypasses probe at ehci-pci.c, then why

You're right; ehci_pci_init isn't needed. But there's no way to

Any problems for that?
No, but it is odd and it requires

Then, it is strange. Do we need even two glue layer drivers for pci
device? Look at usb/chipidea/ci_hdrc_pci.c it has pci_register_driver,
and its host driver will call ehci_init_driver, it is definitely
duplicated with usb/host/ehci-pci.c.

Hi Andy, Would you define pci_id at ci_hdrc_pci.c (instead of ehci-pci.c)

I am not familiar with pci, but it works at other platforms, like ARM.
You can't remove the definition of pci_id in

It depends. How did the code before the adfa79d1c06a commit avoid this
problem? By simply not enabling CONFIG_USB_EHCI_HCD?
