Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 6.9-rc1. Lots of tiny changes and forward progress to support new hardware and better support for existing devices. Included in here are: - Thunderbolt (i.e. USB4) updates for newer hardware and uses as more people start to use the hardware - default USB authentication mode Kconfig and documentation update to make it more obvious what is going on - USB typec updates and enhancements - usual dwc3 driver updates - usual xhci driver updates - function USB (i.e. gadget) driver updates and additions - new device ids for lots of drivers - loads of other small updates, full details in the shortlog All of these, including a "last minute regression fix" have been in linux-next with no reported issues" * tag 'usb-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (185 commits) usb: usb-acpi: Fix oops due to freeing uninitialized pld pointer usb: gadget: net2272: Use irqflags in the call to net2272_probe_fin usb: gadget: tegra-xudc: Fix USB3 PHY retrieval logic phy: tegra: xusb: Add API to retrieve the port number of phy USB: gadget: pxa27x_udc: Remove unused of_gpio.h usb: gadget/snps_udc_plat: Remove unused of_gpio.h usb: ohci-pxa27x: Remove unused of_gpio.h usb: sl811-hcd: only defined function checkdone if QUIRK2 is defined usb: Clarify expected behavior of dev_bin_attrs_are_visible() xhci: Allow RPM on the USB controller (1022:43f7) by default usb: isp1760: remove SLAB_MEM_SPREAD flag usage usb: misc: onboard_hub: use pointer consistently in the probe function usb: gadget: fsl: Increase size of name buffer for endpoints usb: gadget: fsl: Add of device table to enable module autoloading usb: typec: tcpm: add support to set tcpc connector orientatition usb: typec: tcpci: add generic tcpci fallback compatible dt-bindings: usb: typec-tcpci: add tcpci fallback binding usb: gadget: fsl-udc: Replace custom log wrappers by dev_{err,warn,dbg,vdbg} usb: core: Set connect_type of ports based on DT node dt-bindings: usb: Add downstream facing ports to realtek binding ...
