Hi Felipe, Except for Alan's comments, do you agree with this change for common struct, if you agree with it, I will send formal patch with other udc driver's cleanup. looks good to me. Will you provide patches to all other UDC drivers ? it's certainly not mandatory, and I can help with both musb and dwc3 (probably a few others too), but it'll help me if you do. :-) I will do it for all udcs.

[RFC PATCH 0/4] usb: gadget: add is_selfpowered
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.
