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. This new patch set was tested and validated in my environment: - Intel Merrifield was able to use DWC3/f_fs with adbd service (it wasn't before). Changes from v45 to v6: - Updated patches from Michal Nazarewicz to address comments from Alan Stern and mine. - Modified patch 5/5 to apply request->length's pad internally to DWC3. --- David Cohen (3): 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: dwc3: implement gadget's quirk ep_out_align_size Michal Nazarewicz (2): usb: gadget: f_fs: remove loop from I/O function check quirk to pad epout buf size when not aligned to maxpacketsize drivers/usb/dwc3/core.h | 6 +++ drivers/usb/dwc3/gadget.c | 23 ++++++++++ drivers/usb/gadget/f_fs.c | 102 +++++++++++++++++++++------------------------ include/linux/usb/gadget.h | 35 ++++++++++++---- 4 files changed, 103 insertions(+), 63 deletions(-) -- 1.8.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
