Merge tag 'usb-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB and Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt driver changes for 5.12-rc1. It's been an active set of development in these subsystems for the past few months: - loads of typec features added for new hardware - xhci features and bugfixes - dwc3 features added for more hardware support - dwc2 fixes and new hardware support - cdns3 driver updates for more hardware support - gadget driver cleanups and minor fixes - usb-serial fixes, new driver, and more devices supported - thunderbolt feature additions for new hardware - lots of other tiny fixups and additions The chrome driver changes are in here as well, as they depended on some of the typec changes, and the maintainer acked them. All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (300 commits) dt-bindings: usb: mediatek: musb: add mt8516 compatbile dt-bindings: usb: mtk-xhci: add compatible for mt2701 and mt7623 dt-bindings: usb: mtk-xhci: add optional assigned clock properties Documentation: connector: Update the description of sink-vdos usb: misc: usb3503: Fix logic in usb3503_init() dt-bindings: usb: usb-device: fix typo in required properties usb: Replace lkml.org links with lore dt-bindings: usb: dwc3: add description for rk3328 dt-bindings: usb: convert rockchip,dwc3.txt to yaml usb: quirks: add quirk to start video capture on ELMO L-12F document camera reliable USB: quirks: sort quirk entries USB: serial: drop bogus to_usb_serial_port() checks USB: serial: make remove callback return void USB: serial: drop if with an always false condition usb: gadget: Assign boolean values to a bool variable usb: typec: tcpm: Get Sink VDO from fwnode dt-bindings: connector: Add SVDM VDO properties usb: typec: displayport: Fill the negotiated SVDM Version in the header usb: typec: ucsi: Determine common SVDM Version usb: typec: tcpm: Determine common SVDM Version ...
