Merge tag 'usb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY driver updates from Greg KH: "Here are the large set of USB and PHY driver updates for 5.8-rc1. Nothing huge, just lots of little things: - USB gadget fixes and additions all over the place - new PHY drivers - PHY driver fixes and updates - XHCI driver updates - musb driver updates - more USB-serial driver ids added - various USB quirks added - thunderbolt minor updates and fixes - typec updates and additions All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (245 commits) usb: dwc3: meson-g12a: fix USB2 PHY initialization on G12A and A1 SoCs usb: dwc3: meson-g12a: fix error path when fetching the reset line fails Revert "dt-bindings: usb: qcom,dwc3: Convert USB DWC3 bindings" Revert "dt-bindings: usb: qcom,dwc3: Add compatible for SC7180" Revert "dt-bindings: usb: qcom,dwc3: Introduce interconnect properties for Qualcomm DWC3 driver" USB: serial: ch341: fix lockup of devices with limited prescaler USB: serial: ch341: add basis for quirk detection CDC-ACM: heed quirk also in error handling USB: serial: option: add Telit LE910C1-EUX compositions usb: musb: Fix runtime PM imbalance on error usb: musb: jz4740: Prevent lockup when CONFIG_SMP is set usb: musb: mediatek: add reset FADDR to zero in reset interrupt handle usb: musb: use true for 'use_dma' usb: musb: start session in resume for host port usb: musb: return -ESHUTDOWN in urb when three-strikes error happened USB: serial: qcserial: add DW5816e QDL support thunderbolt: Add trivial .shutdown usb: dwc3: keystone: Turn on USB3 PHY before controller dt-bindings: usb: ti,keystone-dwc3.yaml: Add USB3.0 PHY property dt-bindings: usb: convert keystone-usb.txt to YAML ...
