Merge tag 'usb-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1. Nothing major in here, lots of little things with new devices supported and updates for a few drivers. Highlights include: - thunderbolt/USB4 devices supported a bit better than before, and some new ids to enable new hardware devices - USB gadget uvc updates for newer video formats and better v4l integration (the v4l portions were acked by those maintainers) - typec updates for tiny issues and more typec drivers for new chips. - xhci tiny updates for minor issues - big usb-serial ftdi_sio driver update to handle new devices better - lots of tiny dwc3 fixes and updates for the IP block that is showing up everywhere these days - dts updates for new devices being supported - other tiny janitorial and cleanups fixes for lots of different USB drivers. Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'usb-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (169 commits) usb: gadget: uvc: don't put item still in use usb: gadget: uvc: Fix argument to sizeof() in uvc_register_video() usb: host: ehci-exynos: switch to using gpiod API Revert "usb: dwc3: Don't switch OTG -> peripheral if extcon is present" Revert "USB: fixup for merge issue with "usb: dwc3: Don't switch OTG -> peripheral if extcon is present"" dt-bindings: usb: Convert FOTG210 to dt schema usb: mtu3: fix failed runtime suspend in host only mode USB: omap_udc: Fix spelling mistake: "tranceiver_ctrl" -> "transceiver_ctrl" usb: typec: ucsi_ccg: Disable UCSI ALT support on Tegra usb: typec: Replace custom implementation of device_match_fwnode() usb: typec: ucsi: Don't warn on probe deferral usb: add quirks for Lenovo OneLink+ Dock MAINTAINERS: switch dwc3 to Thinh usb: idmouse: fix an uninit-value in idmouse_open USB: PHY: JZ4770: Switch to use dev_err_probe() helper usb: phy: generic: Switch to use dev_err_probe() helper usb: ulpi: use DEFINE_SHOW_ATTRIBUTE to simplify ulpi_regs usb: cdns3: remove dead code usb: cdc-wdm: Use skb_put_data() instead of skb_put/memcpy pair usb: musb: sunxi: Switch to use dev_err_probe() helper ...
