Interesting. This is actually a couple different things ... the OTG related bits would IMO be good to split out from the EHCI ones, and from the OHCI ones. Maybe once 2.6.15 gets out you'd split these out a bit? > Special thanks to Pete Popov and his merry band of kernel hackers for > paving the way by pushing to seperate EHCI and PCI in the USB subsystem. Actually that patch started with Matt Porter, although some earlier non-mergeable versions came from ARC (now TDI). And splitting it out turned up a bunch of problems, mostly now fixed. > Note that the AU1200 does support UDC/OTG as well, but thats another patch > for another day. :) Actually you included a preview in this patch. Interesting ... that makes three OTG implementations I've seen on Linux ... the second highspeed one, too. I think you shouldn't need that OTG_HIGHSPEED symbol, given there's already USB_OTG and USB_GADGET_DUALSPEED, that's implicit. And in fact, it'd be implicit inside EHCI given just USB_OTG! That OTG stuff needs work yet. No <linux/usb.h> changes should be needed, and I'm not sure what this "relaxed whitelist" is for. But by the time those answers are apparent, I expect you'll have give us mergeable patches for OHCI, EHCI, and the UDC. ;) - Dave ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
