Hello,

I want to convert our AT91 OHCI driver to Driver Model, but I am not sure whether OHCI is fully supported or not in Driver Model. From what I can see in `drivers/usb/host/` there are some OHCI drivers registered into Driver Model, but the documentation[1] (perhaps outdated) seems to specify that OHCI is not supported.

Could you please tell me what is the current status of OHCI with Driver Model?

Hello,

My apologies, Simon, I forgot to add you to cc. Do you happen to know the answer to my question?

Hi Tom,

You have been asking about this

Yes, I guess the documentation is out of date. With the exception of ohci-at91 and ohci-lpc32xx all of the other drivers support DM. The ohci-da8xx implementation is likely the easiest one to follow as it didn't do any rewriting but rather added a probe function and data structures to otherwise make use of the existing callers.

It would be better to do a bigger re-org of the code as at this point DM_USB migration deadline has passed so all boards should be fixed up when updating the ohci-at91 driver. Thanks.
