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 v6 to v7: - Downgraded patch set version to v5 as per Felipe Balbi request, with some changes: - usb_ep_align_maxpacketsize() macro was change to usp_ep_align_maybe() in order to check gadget->quirk_ep_out_aligned_size internally. - updated patch 4/5 to use new macro usp_ep_align_maybe() and to fix following compilation warning: $ drivers/usb/gadget/f_fs.c: In function 'ffs_epfile_io': $ drivers/usb/gadget/f_fs.c:857:124: warning: comparison of distinct pointer types lacks a cast [enabled by default]
--- 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: set gadget's quirk ep_out_align_size
Michal Nazarewicz (2): usb: gadget: f_fs: remove loop from I/O function usb: f_fs: check quirk to pad epout buf size when not aligned to maxpacketsize
