Merge tag 'usb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH: "Here is the big set of USB patches for 5.4-rc1. Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things. The usual gadget and xhci and usb serial driver updates, along with a bunch of sysfs file cleanups due to the driver core changes to support that. Nothing really major, just constant forward progress. All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (159 commits) USB: usbcore: Fix slab-out-of-bounds bug during device reset usb: cdns3: Remove redundant dev_err call in cdns3_probe() USB: rio500: Fix lockdep violation USB: rio500: simplify locking usb: mtu3: register a USB Role Switch for dual role mode usb: common: add USB GPIO based connection detection driver usb: common: create Kconfig file usb: roles: get usb-role-switch from parent usb: roles: Add fwnode_usb_role_switch_get() function device connection: Add fwnode_connection_find_match() usb: roles: Introduce stubs for the exiting functions in role.h dt-bindings: usb: mtu3: add properties about USB Role Switch dt-bindings: usb: add binding for USB GPIO based connection detection driver dt-bindings: connector: add optional properties for Type-B dt-binding: usb: add usb-role-switch property usbip: Implement SG support to vhci-hcd and stub driver usb: roles: intel: Enable static DRD mode for role switch xhci-ext-caps.c: Add property to disable Intel SW switch usb: dwc3: remove generic PHY calibrate() calls usb: core: phy: add support for PHY calibration ...

- * It was way too smart of the spec writers not to think that it would
- * be impossible for a generic driver to skip over vendor specific
- * events/notifications if there are no LENGTH fields in the HEADER of
- * each message...the transaction size cannot be counted on as the
- * spec does not forbid to pack more than one event in a single
- * transaction.
- *
- * Thus, we guess sizes with tables (or for events, when you know the
- * size ahead of time you can use uwb_rc_neh_extra_size*()). We
- * register tables with the known events and their sizes, and then we
- * traverse those tables. For those with variable length, we provide a
- * way to lookup the size inside the event/notification's
- * payload. This allows device-specific event size tables to be
- * registered.
- *
- * @size: Size of the payload
- *
- * @offset: if != 0, at offset @offset-1 starts a field with a length
- * that has to be added to @size. The format of the field is
- * given by @type.
- *
- * @type: Type and length of the offset field. Most common is LE 16
- * bits (that's why that is zero); others are there mostly to
- * cover for bugs and weirdos.

- * UMC (UWB Multi-interface Controller) capabilities (e.g., radio

- *
- * The radio controller is not strictly a UMC capability but it's

- *
- * How this works is kind of convoluted but simple. The whci.ko driver
- * loads when WHCI devices are detected. These WHCI devices expose
- * many devices in the same PCI function (they couldn't have reused
- * functions, no), so for each PCI function that exposes these many
- * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
- * with umc_device_create() and adds it to the bus with
- * umc_device_register().
- *
- * umc_device_register() calls device_register() which will push the
- * bus management code to load your UMC driver's somehting_probe()
- * that you have registered for that capability code.
- *
- * Now when the WHCI device is removed, whci_remove() will go over
- * each umc_dev assigned to each of the PCI function's capabilities
- * and through whci_del_cap() call umc_device_unregister() each
- * created umc_dev. Of course, if you are bound to the device, your
