Merge tag 'usb-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt driver updates from Greg KH: "Here is the big set of USB and Thunderbolt driver updates for 6.5-rc1. Included in here are: - Lots of USB4/Thunderbolt additions and updates for new hardware types and fixes as people are starting to get access to the hardware in the wild - new gadget controller driver, cdns2, added - new typec drivers added - xhci driver updates - typec driver updates - usbip driver fixes - usb-serial driver updates and fixes - lots of smaller USB driver updates All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (265 commits) usb: host: xhci-plat: Set XHCI_STATE_REMOVING before resuming XHCI HC usb: host: xhci: Do not re-initialize the XHCI HC if being removed usb: typec: nb7vpq904m: fix CONFIG_DRM dependency usbip: usbip_host: Replace strlcpy with strscpy usb: dwc3: gadget: Propagate core init errors to UDC during pullup USB: serial: option: add LARA-R6 01B PIDs usb: ulpi: Make container_of() no-op in to_ulpi_dev() usb: gadget: legacy: fix error return code in gfs_bind usb: typec: fsa4480: add support for Audio Accessory Mode usb: typec: fsa4480: rework mux & switch setup to handle more states usb: typec: ucsi: call typec_set_mode on non-altmode partner change USB: gadget: f_hid: make hidg_class a static const structure USB: gadget: f_printer: make usb_gadget_class a static const structure USB: mon: make mon_bin_class a static const structure USB: gadget: udc: core: make udc_class a static const structure USB: roles: make role_class a static const structure dt-bindings: usb: dwc3: Add interrupt-names property support for wakeup interrupt dt-bindings: usb: Add StarFive JH7110 USB controller dt-bindings: usb: dwc3: Add IPQ9574 compatible usb: cdns2: Fix spelling mistake in a trace message "Wakupe" -> "Wakeup" ...
