Hi,
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.
Changes from v3 to v4:
- replace u32 quirk flags by single unsigned:1 flag for ep out aligned size
quirk on usb_gadget
- add static inline helper to align ep out buf size

David Cohen (4):
usb: gadget: move bitflags to the end of usb_gadget struct
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
maxpacketsize
usb: dwc3: add quirk USB_GADGET_QUIRK_EP_OUT_ALIGNED_SIZE to gadget
