Hi Felipe, We can use a common is_selfpowered flag at usb_gadget to indicate whether the gadget is self-powered or bus-powered, it can avoid every udc driver defining a similar flag, and the user can read it through udc core sys entry. In the 1st patch, I introduce is_selfpowered for usb_gadget. In the 2nd patch, I take chipidea driver as an example to show how udc driver uses this flag. In the 3rd patch, I clean up at91 udc driver for this flag. In the 4th patch, I add this entry to sys through udc core. If you agree with this change, I will submit a formal patch set after cleaning up other udc drivers.
