Changes for v2: - Keep the placement of struct usb_udc definition unchanging - Add Alan's Ack for patch 1/3
Hi Felipe & Alan: It is the follow-up: http://marc.info/?l=linux-usb&m=142301743123434&w=2 In the first patch, I follow Alan's suggestion that store usb_udc pointer in struct usb_gadget, it will help to find usb_udc according to usb_gadget easlier (Using iterates usb_udc list way will meet lock udc_lock twice problem). In the second patch, I introduce the API usb_udc_vbus_handler, the udc driver can call it if it wants to let the udc core control dp according to vbus. In the third patch, I add the user chipidea for using usb_udc_vbus_handler, after applying this new API, all other dp control code can be deleted except for .pullup API. Thanks.
