Merge tag 'usb-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB and Thunderbolt driver updates from Greg KH: "Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1. Overall, thanks to the removal of a driver, more lines were removed than added, a nice change. Highlights include: - removal of the sisusbvga driver that was not used by anyone anymore - minor thunderbolt driver changes and tweaks - chipidea driver updates - usual set of typec driver features and hardware support added - musb minor driver fixes - fotg210 driver fixes, bringing that hardware back from the "dead" - minor dwc3 driver updates - addition, and then removal, of a list.h helper function for many USB and other subsystem drivers, that ended up breaking the build. That will come back for 6.3-rc1, it missed this merge window. - usual xhci updates and enhancements - usb-serial driver updates and support for new devices - other minor USB driver updates All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (153 commits) usb: gadget: uvc: Rename bmInterfaceFlags -> bmInterlaceFlags usb: dwc2: power on/off phy for peripheral mode in dual-role mode usb: dwc2: disable lpm feature on Rockchip SoCs dt-bindings: usb: mtk-xhci: add support for mt7986 usb: dwc3: core: defer probe on ulpi_read_id timeout usb: ulpi: defer ulpi_register on ulpi_read_id timeout usb: misc: onboard_usb_hub: add Genesys Logic GL850G hub support dt-bindings: usb: Add binding for Genesys Logic GL850G hub controller dt-bindings: vendor-prefixes: add Genesys Logic usb: fotg210-udc: fix potential memory leak in fotg210_udc_probe() usb: typec: tipd: Set mode of operation for USB Type-C connector usb: gadget: udc: drop obsolete dependencies on COMPILE_TEST usb: musb: remove extra check in musb_gadget_vbus_draw usb: gadget: uvc: Prevent buffer overflow in setup handler usb: dwc3: qcom: Fix memory leak in dwc3_qcom_interconnect_init usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe() usb: storage: Add check for kcalloc USB: sisusbvga: use module_usb_driver() USB: sisusbvga: rename sisusb.c to sisusbvga.c USB: sisusbvga: remove console support ...

-Microchip USB 2.0 Hi-Speed Hub Controller
-
-The device node for the configuration of a Microchip USB251x/xBi USB 2.0
-Hi-Speed Controller.
-
-Required properties :
- - compatible : Should be "microchip,usb251xb" or one of the specific types:
- "microchip,usb2512b", "microchip,usb2512bi", "microchip,usb2513b",
- "microchip,usb2513bi", "microchip,usb2514b", "microchip,usb2514bi",
- "microchip,usb2517", "microchip,usb2517i", "microchip,usb2422"
- - reg : I2C address on the selected bus (default is <0x2C>)
-
-Optional properties :
- - reset-gpios : Should specify the gpio for hub reset
- - vdd-supply : Should specify the phandle to the regulator supplying vdd
- - skip-config : Skip Hub configuration, but only send the USB-Attach command
- - vendor-id : Set USB Vendor ID of the hub (16 bit, default is 0x0424)
- - product-id : Set USB Product ID of the hub (16 bit, default depends on type)
- - device-id : Set USB Device ID of the hub (16 bit, default is 0x0bb3)
- - language-id : Set USB Language ID (16 bit, default is 0x0000)
- - manufacturer : Set USB Manufacturer string (max 31 characters long)
- - product : Set USB Product string (max 31 characters long)
- - serial : Set USB Serial string (max 31 characters long)
- - {bus,self}-powered : selects between self- and bus-powered operation
- (boolean, default is self-powered)
- - disable-hi-speed : disable USB Hi-Speed support (boolean)
- - {multi,single}-tt : selects between multi- and single-transaction-translator
- (boolean, default is multi-tt)
- - disable-eop : disable End of Packet generation in full-speed mode (boolean)
- - {ganged,individual}-sensing : select over-current sense type in self-powered
- mode (boolean, default is individual)
- - {ganged,individual}-port-switching : select port power switching mode
- (boolean, default is individual)
- - dynamic-power-switching : enable auto-switching from self- to bus-powered
- operation if the local power source is removed or unavailable (boolean)
- - oc-delay-us : Delay time (in microseconds) for filtering the over-current
- sense inputs. Valid values are 100, 4000, 8000 (default) and 16000. If
- an invalid value is given, the default is used instead.
- - compound-device : indicate the hub is part of a compound device (boolean)
- - port-mapping-mode : enable port mapping mode (boolean)
- - led-{usb,speed}-mode : led usb/speed indication mode selection
- (boolean, default is speed mode)
- - string-support : enable string descriptor support (required for manufacturer,
- product and serial string configuration)
