Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 7.1-rc1. Lots of little things in here, nothing major, just constant improvements, updates, and new features. Highlights are: - new USB power supply driver support. These changes did touch outside of drivers/usb/ but got acks from the relevant mantainers for them. - dts file updates and conversions - string function conversions into "safer" ones - new device quirks - xhci driver updates - usb gadget driver minor fixes - typec driver additions and updates - small number of thunderbolt driver changes - dwc3 driver updates and additions of new hardware support - other minor driver updates All of these have been in the linux-next tree for a while with no reported issues" * tag 'usb-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (176 commits) usb: dwc3: starfive: Add JHB100 USB 2.0 DRD controller dt-bindings: usb: dwc3: add support for StarFive JHB100 dt-bindings: usb: atmel,at91sam9rl-udc: convert to DT schema dt-bindings: usb: atmel,at91rm9200-udc: convert to DT schema dt-bindings: usb: generic-ehci: fix schema structure and add at91sam9g45 constraints dt-bindings: usb: generic-ohci: add AT91RM9200 OHCI binding support arm: dts: at91: remove unused #address-cells/#size-cells from sam9x60 udc node drivers/usb/host: Fix spelling error 'seperate' -> 'separate' usbip: tools: add hint when no exported devices are found USB: serial: iuu_phoenix: fix iuutool author name usb: gadget: f_ncm: validate minimum block_len in ncm_unwrap_ntb() usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete() usb: gadget: f_hid: Add missing error code usb: typec: cros_ec_ucsi: Load driver from OF and ACPI definitions dt-bindings: chrome: Add cros-ec-ucsi compatibility to typec binding USB: of: Simplify with scoped for each OF child loop usbip: validate number_of_packets in usbip_pack_ret_submit() usb: gadget: renesas_usb3: validate endpoint index in standard request handlers usb: core: config: reverse the size check of the SSP isoc endpoint descriptor usb: typec: ucsi: Set usb mode on partner change ...

usb: typec: ucsi: Set usb mode on partner change

2026-04-07T11:47:59+00:00

Currently the partner usb_mode is only set in ucsi_register_partner(). If the partner enters USB4 operation after it is registered, this is not reported to the typec class. The UCSI spec states that the Connector Partner Changed bit can represent a Connector Partner Flags change. When handling a UCSI partner change, check the partner flags for USB4 operation.

usb: typec: ucsi: skip connector validation before init

2026-04-07T11:35:44+00:00

Notifications can arrive before ucsi_init() has populated ucsi->cap.num_connectors via GET_CAPABILITY. At that point num_connectors is still 0, causing all valid connector numbers to be incorrectly rejected as bogus. Skip the bounds check when num_connectors is 0 (not yet initialized). Pre-init notifications are already handled safely by the early-event guard in ucsi_connector_change().

usb: typec: thunderbolt: Set enter_vdo during initialization

2026-03-30T15:17:40+00:00

In the current implementation, if a cable's alternate mode enter operation is not supported, the tbt->plug[TYPEC_PLUG_SOP_P] pointer is cleared by the time tbt_enter_mode() is called. This prevents the driver from identifying the cable's VDO. As a result, the Thunderbolt connection falls back to the default TBT_CABLE_USB3_PASSIVE speed, even if the cable supports higher speeds. To ensure the correct VDO value is used during mode entry, calculate and store the enter_vdo earlier during the initialization phase in tbt_ready().

usb: typec: Remove alt->adev.dev.class assignment

2026-03-30T15:17:21+00:00

The typec plug alternate mode is already registered as part of the bus. When both class and bus are set for a device, device_add() attempts to create the "subsystem" symlink in the device's sysfs directory twice, once for the bus and once for the class. This results in a duplicate filename error during registration, causing the alternate mode registration to fail with warnings: cannot create duplicate filename '/devices/pci0000:00/0000:00:1f.0/ PNP0C09:00/GOOG0004:00/cros-ec-dev.1.auto/cros_ec_ucsi.3.auto/typec/ port1/port1-cable/port1-plug0/port1-plug0.0/subsystem' typec port0-plug0: failed to register alternate mode (-17) cros_ec_ucsi.3.auto: failed to registers svid 0x8087 mode 1 Cc: stable Fixes: 67ab45426215 ("usb: typec: Set the bus also for the port and plug altmodes") Tested-by: Madhu M Signed-off-by: Andrei Kuchynski Reviewed-by: Heikki Krogerus Reviewed-by: Benson Leung Link: https://patch.msgid.link/20260324102903.1416210-1-akuchynski@chromium.org Signed-off-by: Greg Kroah-Hartman

usb: typec: tcpm/tcpci_maxim: deprecate WAR for setting charger mode

2026-03-30T14:58:33+00:00

TCPCI maxim driver directly writes to the charger's register space to set charger mode depending on the power role. As MAX77759 chg driver exists, this WAR is not required. Instead, use a regulator interface to source vbus when typec is in source power mode. In other power modes, this regulator will be turned off if active.

FUSB302 fails to probe with -EINVAL if its interrupt line is connected via an I2C GPIO expander, such as TI TCA6416.

usb: typec: tcpci_rt1711h: Drop unnecessary VID/PID/DID checks

2026-03-30T14:53:11+00:00

Existing checks for VID/PID/DID in the driver are redundant since the driver is already matched to the device via I2C device ID and OF compatible strings, and they preclude the use of fallback compatibles. Remove them to make the driver slimmer and adding new clones easier.
