usb: common: move function's kerneldoc next to its definition

2022-10-26T11:25:31+00:00

[ Upstream commit 365038f24b3e9d2b7c9e499f03f432040e28a35c ] Following a general rule, add the kerneldoc for a function next to it's definition, but not next to its declaration in a header file.

usb: common: Parse for USB SSP genXxY

2022-10-26T11:25:30+00:00

[ Upstream commit 52c2d15703c3a900d5f78cd599b823db40d5100b ] The USB "maximum-speed" property can now take the SSP signaling rate generation and lane count with these new strings: "super-speed-plus-gen2x2" "super-speed-plus-gen2x1" "super-speed-plus-gen1x2" Introduce usb_get_maximum_ssp_rate() to parse for the corresponding usb_ssp_rate enum. The original usb_get_maximum_speed() will return USB_SPEED_SUPER_PLUS if it matches one of these new strings.

USB: move usb debugfs directory creation to the usb common core

2019-06-06T06:59:19+00:00

The USB gadget subsystem wants to use the USB debugfs root directory, so move it to the common "core" USB code so that it is properly initialized and removed as needed. In order to properly do this, we need to load the common code before the usb core code, when everything is linked into the kernel, so reorder the link order of the code. Also as the usb common code has the possibility of the led trigger logic to be merged into it, handle the build option properly by only having one module init/exit function and have the common code initialize the led trigger if needed.

usb: introduce usb_ep_type_string() function

2019-03-26T07:45:03+00:00

In some places, the code prints a human-readable USB endpoint transfer type (e.g. "bulk"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To make this scenario easier, here introduces usb_ep_type_string() function, which returns a human-readable name of provided endpoint type. It also changes a few places switch was used to use this new function. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: common: Consider only available nodes for dr_mode

2019-03-19T13:57:32+00:00

There are cases where multiple device tree nodes point to the same phy node by means of the "phys" property, but we should only consider those nodes that are marked as available rather than just any node.

usb: Change usb_of_get_companion_dev() place to usb/common

2018-09-10T18:40:29+00:00

Since renesas_usb3 udc driver calls usb_of_get_companion_dev() which is on usb/core/of.c, build error like below happens if we disable CONFIG_USB because the usb/core/ needs CONFIG_USB: ERROR: "usb_of_get_companion_dev" [drivers/usb/gadget/udc/renesas_usb3.ko] undefined! According to the usb/gadget/Kconfig, "NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!". So, to fix the issue, this patch changes the usb_of_get_companion_dev() place from usb/core/of.c to usb/common/common.c to be called by both host and gadget.

USB: common: Remove redundant license text

2017-11-04T10:55:39+00:00

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/

2017-11-04T10:48:02+00:00

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.
