Merge tag 'usb-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt updates from Greg KH: "Here is the big USB and thunderbolt pull request for 5.11-rc1. Nothing major in here, just the grind of constant development to support new hardware and fix old issues: - thunderbolt updates for new USB4 hardware - cdns3 major driver updates - lots of typec updates and additions as more hardware is available - usb serial driver updates and fixes - other tiny USB driver updates All have been in linux-next with no reported issues" * tag 'usb-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits) usb: phy: convert comma to semicolon usb: ucsi: convert comma to semicolon usb: typec: tcpm: convert comma to semicolon usb: typec: tcpm: Update vbus_vsafe0v on init usb: typec: tcpci: Enable bleed discharge when auto discharge is enabled usb: typec: Add class for plug alt mode device USB: typec: tcpci: Add Bleed discharge to POWER_CONTROL definition USB: typec: tcpm: Add a 30ms room for tPSSourceOn in PR_SWAP USB: typec: tcpm: Fix PR_SWAP error handling USB: typec: tcpm: Hard Reset after not receiving a Request USB: gadget: f_fs: remove likely/unlikely usb: gadget: f_fs: Re-use SS descriptors for SuperSpeedPlus USB: gadget: f_midi: setup SuperSpeed Plus descriptors USB: gadget: f_acm: add support for SuperSpeed Plus USB: gadget: f_rndis: fix bitrate for SuperSpeed and above usb: typec: intel_pmc_mux: Configure cable generation value for USB4 MAINTAINERS: Add myself as a reviewer for CADENCE USB3 DRD IP DRIVER usb: chipidea: ci_hdrc_imx: Use of_device_get_match_data() usb: chipidea: usbmisc_imx: Use of_device_get_match_data() usb: cdns3: fix NULL pointer dereference on no platform data ...
