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

2019-06-06T06:59:19Z

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

2019-03-26T07:45:03Z

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

2019-03-19T13:57:32Z

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

2018-09-10T18:40:29Z

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

2017-11-04T10:55:39Z

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: common: use of_property_read_bool()

2017-08-28T09:39:31Z

usb: Convert to using %pOF instead of full_name

2017-07-22T13:56:53Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring Acked-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

USB: Fix of_usb_get_dr_mode_by_phy with a shared phy block

2016-06-21T07:52:39Z

Some SoCs have a single phy-hw-block with multiple phys, this is modelled by a single phy dts node, so we end up with multiple controller nodes with a phys property pointing to the phy-node of the otg-phy. Only one of these controllers typically is an otg controller, yet we were checking the first controller who uses a phy from the block and then end up looking for a dr_mode property in e.g. the ehci controller. This commit fixes this by adding an arg0 parameter to of_usb_get_dr_mode_by_phy and make of_usb_get_dr_mode_by_phy check that this matches the phandle args[0] value when looking for the otg controller.
