Hi Eddie, > add functions to set and get usb interface descriptor, so people can > customize usb interface descriptor
The f_mass_storage USB function is used through the g_dnl code: ./drivers/usb/gadget/g_dnl.c Other gadget functions - like dfu and thor are using it. Please consider following this scheme - for example look into the Samsung's Thor protocol support at: ./drivers/usb/gadget/f_thor.c Since we managed to add Thor (vendor specific protocol), then it should be doable to add rockusb as well. Another good example of this framework reuse is f_fastboot.c to support Android fastboot protocol. Please consider if rockchip could be added in the same manner. > > Signed-off-by: Eddie Cai <[email protected]> > --- > drivers/usb/gadget/f_mass_storage.c | 18 ++++++++++++++++++ > include/f_mass_storage.h | 2 ++ > 2 files changed, 20 insertions(+) > > diff --git a/drivers/usb/gadget/f_mass_storage.c > b/drivers/usb/gadget/f_mass_storage.c index faf875e..333f069 100644 > --- a/drivers/usb/gadget/f_mass_storage.c > +++ b/drivers/usb/gadget/f_mass_storage.c > @@ -2870,6 +2870,24 @@ static int fsg_bind_config(struct > usb_composite_dev *cdev, return rc; > } > > +struct usb_interface_descriptor > *fsg_get_usb_interface_descriptor(void) +{ To adjust the usb descriptor one can use: g_dnl_bind_fixup() function (defined at g_dnl.c).
