Merge tag 'usb-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/Thunderbolt updates from Greg KH: "Here is the large set of USB and Thunderbolt patches for 5.9-rc1. Nothing really magic/major in here, just lots of little changes and updates: - clean up language usages in USB core and some drivers - Thunderbolt driver updates and additions - USB Gadget driver updates - dwc3 driver updates (like always...) - build with "W=1" warning fixups - mtu3 driver updates - usb-serial driver updates and device ids - typec additions and updates for new hardware - xhci debug code updates for future platforms - cdns3 driver updates - lots of other minor driver updates and fixes and cleanups All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (330 commits) usb: common: usb-conn-gpio: Register charger usb: mtu3: simplify mtu3_req_complete() usb: mtu3: clear dual mode of u3port when disable device usb: mtu3: use MTU3_EP_WEDGE flag usb: mtu3: remove useless member @busy in mtu3_ep struct usb: mtu3: remove repeated error log usb: mtu3: add ->udc_set_speed() usb: mtu3: introduce a funtion to check maximum speed usb: mtu3: clear interrupts status when disable interrupts usb: mtu3: reinitialize CSR registers usb: mtu3: fix macro for maximum number of packets usb: mtu3: remove unnecessary pointer checks usb: xhci: Fix ASMedia ASM1142 DMA addressing usb: xhci: define IDs for various ASMedia host controllers usb: musb: convert to devm_platform_ioremap_resource_byname usb: gadget: tegra-xudc: convert to devm_platform_ioremap_resource_byname usb: gadget: r8a66597: convert to devm_platform_ioremap_resource_byname usb: dwc3: convert to devm_platform_ioremap_resource_byname usb: cdns3: convert to devm_platform_ioremap_resource_byname usb: phy: am335x: convert to devm_platform_ioremap_resource_byname ...
