2021-01-19USB: gadget: udc: Process disconnect synchronouslyDavidlohr Bueso
As the comment in usb_disconnect() hints, do not defer the disconnect processing, and instead just do it directly in the irq handler. This allows the driver to avoid using a nowadays deprecated tasklet.

2020-07-30treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()Kees Cook
This converts all the existing DECLARE_TASKLET() (and ...DISABLED) macros with DECLARE_TASKLET_OLD() in preparation for refactoring the tasklet callback type. All existing DECLARE_TASKLET() users had a "0" data argument, it has been removed here as well.

2020-07-30usb: gadget: udc: Avoid tasklet passing a globalKees Cook
There's no reason for the tasklet callback to set an argument since it always uses a global. Instead, use the global directly, in preparation for converting the tasklet subsystem to modern callback conventions.

2020-07-15usb: gadget: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2017-11-07USB: gadget: udc: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2017-10-17usb/gadget/snps_udc_core: Convert timers to use timer_setup()Kees Cook
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. If the probe fails, udc_remove() will not be called, so there is no reason to make del_timer_sync() calls conditional. As a result, use of the .data field can be dropped, in support of making removing this field entirely from struct timer_list.

2017-06-13usb: gadget: udc: Add Synopsys UDC Platform driverRaviteja Garimella
This patch adds platform driver support for Synopsys UDC. A new driver file (snps_udc_plat.c) is created for this purpose where the platform driver registration is done based on OF node. Currently, UDC integrated into Broadcom's iProc SoCs (Northstar2 and Cygnus) work with this driver. New members are added to the UDC data structure for having platform device support along with extcon and phy support. Kconfig and Makefiles are modified to select platform driver for compilation.
