usb: gadget: g_dnl: don't set iProduct nor iSerialNumber

2017-04-14T14:44:16Z

Both these numbers are calculated in runtime and dynamically assigned to the device descriptor during bind(). Signed-off-by: Felipe Balbi

usb: gadget: g_dnl: only set iSerialNumber if we have a serial#

2017-04-14T14:44:16Z

We don't want to claim that we support a serial number string and later return nothing. Because of that, if g_dnl_serial is an empty string, let's skip setting iSerialNumber to a valid number. Signed-off-by: Felipe Balbi

usb: gadget: g_dnl: hold maximum string descriptor

2017-04-14T14:44:16Z

A USB String descriptor can be up to 255 characters long and it's not NULL terminated according to the USB spec. This means our MAX_STRING_SERIAL should be 256 (to cope with NULL terminator). Signed-off-by: Felipe Balbi

usb: gadget: f_dfu: set serial number if serial# is valid

2017-02-26T12:24:30Z

With this patch, USB Command Verifier is happy with our DFU implementation on Chapter 9 tests. Signed-off-by: Felipe Balbi

usb: gadget: g_dnl: fix g_dnl_set_serialnumber()

2017-02-26T12:24:30Z

instead of only copying if strlen(s) is less than 32 characters, let's just copy at most 31 characters regardless of the size of serial#. This will guarantee that we always have a serial number if serial# environment variable is set to anything. Note that without a proper serial number, USB Command Verifier fails our test of Device Descriptor since we will claim to have a serial number without really providing one when requested.

usb: gadget: f_dfu: write req->actual bytes

2017-02-26T12:24:30Z

If last packet is short, we shouldn't write req->length bytes to non-volatile media, we should write only what's available to us, which is held in req->actual. Signed-off-by: Felipe Balbi Signed-off-by: Andy Shevchenko

usb: gadget: dfu: add result for handle_getstatus()

2017-02-26T12:24:30Z

harmonize result with other handle_XXX() functions: return int for size remove the define RET_STAT_LEN : no more necessary Signed-off-by: Patrick Delaunay Signed-off-by: Patrick Delaunay

usb: gadget: dfu: correct size for USB_REQ_DFU_GETSTATE result

2017-02-26T12:24:30Z

return the correct size for DFU_GETSTATE result (1 byte in DFU 1.1 spec) to avoid issue in USB protocol and the variable "value" is propagated to req->lenght as all the in the other request with answer - DFU_GETSTATUS - DFU_DNLOAD - DFU_UPLOAD Then the buffer is correctly treated in USB driver NB: it was the only request witch directly change "req->actual" Signed-off-by: Patrick Delaunay Signed-off-by: Patrick Delaunay

usb: gadget: dfu: add functional descriptor in descriptor set

2017-02-26T12:24:30Z

The "DFU descriptor set" must contain the "DFU functional descriptor" but it is missing today in U-Boot code (cf: DFU spec 1.1, chapter 4.2 DFU Mode Descriptor Set) This patch only allocate buffer and copy DFU functional descriptor after interfaces.
