[PATCH v3 0/3] add gadget quirk to adapt f_fs for DWC3

From: David Cohen
Date: Wed Oct 30 2013 - 13:04:45 EST


These patches are a proposal to add gadget quirks in an immediate objective to
adapt f_fs when using DWC3 controller. But the quirk solution is generic and
can be used by other controllers to adapt gadget functions to their
non-standard restrictions.

This change is necessary to make Android's adbd service to work on Intel
Merrifield with f_fs instead of out-of-tree android gadget.

David Cohen (3):
usb: gadget: add quirk_ep_out_aligned_size field to struct usb_gadget
usb: ffs: check quirk to pad epout buf size when not aligned to
usb: dwc3: add quirk USB_GADGET_QUIRK_EP_OUT_ALIGNED_SIZE to gadget
