Yes, I guess the documentation is out of date.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. -- Tom
