USB: Fix up terminology

2020-07-01T12:04:04Z

USB is a HOST/DEVICE protocol, as per the specification and all documentation. Fix up terms that are not applicable to make things match up with the terms used through the rest of the USB stack.

USB: gadget: legacy: Remove redundant license text

2017-11-07T14:45:02Z

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.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02Z

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.

usb: gadget: zero: Convert timers to use timer_setup()

2017-11-01T15:57:23Z

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. Adds a static tracking variable to match the timer global. Signed-off-by: Kees Cook Acked-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: gadget: composite: remove redundant bcdUSB setting in legacy

2015-12-15T15:12:41Z

Since composite now overwrites bcdUSB for any gadget, remove setting it in legacy gadgets. All legacy gadgets set 0x0200, the same as the value additionally set by composite, so there is no behaviour change.

usb: gadget: f_sourcesink: add queue depth

usb: gadget: remove incorrect init/exit annotations

2015-04-27T19:45:35Z

A recent change introduced a link error for the composite printer gadget driver: `printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o Evidently the unbind function should not be marked __exit here, because it is called through a callback pointer that is not necessarily discarded, __composite_unbind() is indeed called from the error path of composite_bind(), which can never work for a built-in driver. Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

Revert "usb: gadget: zero: Add support for interrupt EP"

2015-03-11T15:00:05Z

This reverts commit ef11982dd7a657512c362242508bb4021e0d67b6. That commit creates a problem for some UDCs (at least musb) where it allocates an endpoints with a 64-byte FIFO, but later tries to use that same FIFO for 1024-byte packets. Before implementing this, composite framework needs to be modified so we only allocate endpoints after we know negotiated speed, however that needs quite a bit of extra work.
