2020-05-14usb: gadget: g_dnl: add function g_dnl_set_productPatrick Delaunay
Add a function g_dnl_set_product to change the Product string used in USB enumeration in any command based on download gadget. If the function is called with NULL pointer, the product string is set to the default value (product[] = "USB download gadget").

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-09-05usb: gadget: g_dnl: Sync internal SN variable with envSam Protsenko
Since commit 842778a09104 ("usb: gadget: g_dnl: only set iSerialNumber if we have a serial#") "fastboot devices" stopped to show correct device serial number for TI boards, showing this line instead: ???????????? fastboot This is because serial# env variable could be set after g_dnl gadget was initialized (e.g. by using env_set() in the board file). To fix this, let's update internal serial number variable (g_dnl_serial) when "serial#" env var is changed.

2017-06-29usb: gadget: Call g_dnl_bind_fixup() before testing g_dnl_serial lengthLukasz Majewski
After the commit SHA1: 842778a091 - the serial number descriptor is only visible when we have non zero length of g_dnl_serial. However, on some platforms (e.g. Siemens) the serial number is set at g_dnl_bind_fixup(), so with the current code we will always omit the serial (since it is not set). This commit moves the g_dnl_bind_fixup() call before the g_dnl_serial length test.

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 <felipe.balbi@linux.intel.com>
2017-02-26usb: gadget: g_dnl: fix g_dnl_set_serialnumber()Felipe Balbi
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.

2015-09-11usb: gadget: don't leak configs when unbindingStephen Warren
By the time g_dnl_unbind() is run, cdev->config has been set to NULL, so the free() there does nothing, and the config struct is leaked. Equally, struct usb_gadget contains a linked list of config structs, so the code should iterate over them all and free each one, rather than freeing one particular config struct. composite_unbind() already iterates over the list of config structs, and unlinks each from the linked list. Fix this loop to free() each struct as it's unlinked and otherwise forgotten.

2014-05-05USB: gadget: save driver name before registering itStephen Warren
g_dnl_register() currently first attempts to register a composite driver by name, and then saves the driver name once it's registered. Internally to the registration code, g_dnl_do_config() is called and attempts to compare the composite device's name with the list of known device names. This fails since the composite device's name has not yet been stored. This means that the first time "ums 0 0" is run, it fails, but subsequent attempts succeed. Re-order the name-saving and registration code to solve this. Fixes: e5b834e07f51 ("USB: gadget: added a saner gadget downloader registration API") Signed-off-by: Stephen Warren <swarren@nvidia.com>

2014-05-05usb: dfu: fix boards wo USB cable detectionMateusz Zalega
Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.
