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 driver drivers/usb/dwc3/gadget.c | 6 ++++++ drivers/usb/gadget/f_fs.c | 22 ++++++++++++++++++++++ include/linux/usb/gadget.h | 38 +++++++++++++++++++++++++++++--------- 3 files changed, 57 insertions(+), 9 deletions(-) -- 1.8.4.rc3
