Merge tag 'usb-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY/Thunderbolt driver updates from Greg KH: "Here is the big set of USB, PHY, and Thunderbolt driver updates for 5.10-rc1. Lots of tiny different things for these subsystems are in here, including: - phy driver updates - thunderbolt / USB 4 updates and additions - USB gadget driver updates - xhci fixes and updates - typec driver additions and updates - api conversions to various drivers for core kernel api changes - new USB control message functions to make it harder to get wrong, as found by syzbot (took 2 tries to get it right) - lots of tiny USB driver fixes and updates all over the place All of these have been in linux-next for a while, with the exception of the last "obviously correct" patch that updated a FALLTHROUGH comment that got merged last weekend" * tag 'usb-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (374 commits) usb: musb: gadget: Use fallthrough pseudo-keyword usb: typec: Add QCOM PMIC typec detection driver USB: serial: option: add Cellient MPL200 card usb: typec: tcpci_maxim: Add support for Sink FRS usb: typec: tcpci: Implement callbacks for FRS usb: typec: tcpm: Add support for Sink Fast Role SWAP(FRS) usb: typec: tcpci_maxim: Chip level TCPC driver usb: typec: tcpci: Add set_vbus tcpci callback usb: typec: tcpci: Add a getter method to retrieve tcpm_port reference usbip: vhci_hcd: fix calling usb_hcd_giveback_urb() with irqs enabled usb: cdc-acm: add quirk to blacklist ETAS ES58X devices USB: serial: ftdi_sio: use cur_altsetting for consistency USB: serial: option: Add Telit FT980-KS composition USB: core: remove polling for /sys/kernel/debug/usb/devices usb: typec: add support for STUSB160x Type-C controller family usb: typec: add typec_find_pwr_opmode usb: typec: hd3ss3220: Use OF graph API to get the connector fwnode dt-bindings: usb: renesas,usb3-peri: Document HS and SS data bus dt-bindings: usb: convert ti,hd3ss3220 bindings to json-schema usb: dwc2: Fix INTR OUT transfers in DDMA mode. ...
