Merge tag 'usb-5.17-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 5.17-rc1. Nothing major in here, just lots of little updates and cleanups. These include: - some USB header fixes picked from Ingo's header-splitup work - more USB4/Thunderbolt hardware support added - USB gadget driver updates and additions - USB typec additions (includes some acpi changes, which were acked by the ACPI maintainer) - core USB fixes as found by syzbot that were too late for 5.16-final - USB dwc3 driver updates - USB dwc2 driver updates - platform_get_irq() conversions of some USB drivers - other minor USB driver updates and additions All of these have been in linux-next for a while with no reported issues" * tag 'usb-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (111 commits) docs: ABI: fixed formatting in configfs-usb-gadget-uac2 usb: gadget: u_audio: Subdevice 0 for capture ctls usb: gadget: u_audio: fix calculations for small bInterval usb: dwc2: gadget: initialize max_speed from params usb: dwc2: do not gate off the hardware if it does not support clock gating usb: dwc3: qcom: Fix NULL vs IS_ERR checking in dwc3_qcom_probe headers/deps: USB: Optimize <linux/usb/ch9.h> dependencies, remove <linux/device.h> USB: common: debug: add needed kernel.h include headers/prep: Fix non-standard header section: drivers/usb/host/ohci-tmio.c headers/prep: Fix non-standard header section: drivers/usb/cdns3/core.h headers/prep: usb: gadget: Fix namespace collision USB: core: Fix bug in resuming hub's handling of wakeup requests USB: Fix "slab-out-of-bounds Write" bug in usb_hcd_poll_rh_status usb: dwc3: dwc3-qcom: Add missing platform_device_put() in dwc3_qcom_acpi_register_core usb: gadget: clear related members when goto fail usb: gadget: don't release an existing dev->buf usb: dwc2: Simplify a bitmap declaration usb: Remove usb_for_each_port() usb: typec: port-mapper: Convert to the component framework usb: Link the ports to the connectors they are attached to ...

-Xilinx SuperSpeed DWC3 USB SoC controller
-
-Required properties:
-- compatible: May contain "xlnx,zynqmp-dwc3" or "xlnx,versal-dwc3"
-- reg: Base address and length of the register control block
-- clocks: A list of phandles for the clocks listed in clock-names
-- clock-names: Should contain the following:
- "bus_clk" Master/Core clock, have to be >= 125 MHz for SS
- operation and >= 60MHz for HS operation
-
- "ref_clk" Clock source to core during PHY power down
-- resets: A list of phandles for resets listed in reset-names
-- reset-names:
- "usb_crst" USB core reset
- "usb_hibrst" USB hibernation reset
- "usb_apbrst" USB APB reset
-
-Required child node:
-A child node must exist to represent the core DWC3 IP block. The name of
-the node is not important. The content of the node is defined in dwc3.txt.
-
-Optional properties for snps,dwc3:
-- dma-coherent: Enable this flag if CCI is enabled in design. Adding this
- flag configures Global SoC bus Configuration Register and
- Xilinx USB 3.0 IP - USB coherency register to enable CCI.
-- interrupt-names: Should contain the following:
- "dwc_usb3" USB gadget mode interrupts
- "otg" USB OTG mode interrupts
- "hiber" USB hibernation interrupts
-
