Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and thunderbolt drivers for 6.18-rc1. It was another normal development cycle, with lots of the usual drivers getting updates: - Thunderbolt driver cleanups and additions - dwc3 driver updates - dwc2 driver updates - typec driver updates - xhci driver updates and additions - offload USB engine updates for better power management - unused tracepoint removals - usb gadget fixes and updates as more users start to rely on these drivers instead of the "old" function gadget drivers - new USB device ids - other minor driver USB driver updates - new USB I/O driver framework and driver additions" The last item, the usb i/o driver, has an i2c and gpio driver added through this tree. Those drivers were acked by the respective subsystem maintainers.

Merge patch series "usb: gadget: Refactor function drivers to use __free() cleanup"

2025-09-17T10:44:55Z

Kuen-Han Tsai says: This patch series refactors the error-handling paths in the bind() function for f_ncm, f_acm, f_ecm, and f_rndis drivers. The current, unified goto logic in these drivers is vulnerable to a null pointer dereference. This is caused by the cleanup logic incorrectly handling the stale usb_request pointer after a bind/unbind cycle. This series fixes this issue by converting the drivers to use the modern __free() scope-based cleanup mechanism. Patches 1-2 are preparatory, adding the endpoint pointer to struct usb_request and defining helpers for the __free() cleanup. The remaining four patches use this new plumbing to refactor each driver. Future work ----------- 1. Refactor usb_ep_free_request(), usb_ep_queue(), and usb_ep_dequeue() functions as the ep parameter becomes redudant. 2. Convert the remaining gadget function drivers to use the new __free() cleanup mechanism. Link: https://lore.kernel.org/r/20250916-ready-v1-0-4997bf277548@google.com Signed-off-by: Greg Kroah-Hartman

usb: gadget: Introduce free_usb_request helper

2025-09-17T10:44:53Z

Introduce the free_usb_request() function that frees both the request's buffer and the request itself. This function serves as the cleanup callback for DEFINE_FREE() to enable automatic, scope-based cleanup for usb_request pointers.

usb: gadget: Store endpoint pointer in usb_request

2025-09-17T10:44:53Z

Gadget function drivers often have goto-based error handling in their bind paths, which can be bug-prone. Refactoring these paths to use __free() scope-based cleanup is desirable, but currently blocked. The blocker is that usb_ep_free_request(ep, req) requires two parameters, while the __free() mechanism can only pass a pointer to the request itself. Store an endpoint pointer in the struct usb_request. The pointer is populated centrally in usb_ep_alloc_request() on every successful allocation, making the request object self-contained.

Merge patch series "Support system sleep with offloaded usb transfers" into usb-next

2025-09-12T12:08:09Z

Guan-Yu Lin says: Wesley Cheng and Mathias Nyman's USB offload design enables a co-processor to handle some USB transfers, potentially allowing the system to sleep (suspend-to-RAM) and save power. However, Linux's System Sleep model halts the USB host controller when the main system isn't managing any USB transfers. To address this, the proposal modifies the system to recognize offloaded USB transfers and manage power accordingly. This way, offloaded USB transfers could still happen during system sleep (Suspend-to-RAM). This involves two key steps: 1. Transfer Status Tracking: Propose offload_usage and corresponding apis drivers could track USB transfers on the co-processor, ensuring the system is aware of any ongoing activity. 2. Power Management Adjustment: Modifications to the USB driver stack (xhci host controller driver, and USB device drivers) allow the system to sleep (Suspend-to-RAM) without disrupting co-processor managed USB transfers. This involves adding conditional checks to bypass some power management operations in the System Sleep model.

xhci: sideband: add api to trace sideband usage

2025-09-12T12:08:02Z

The existing sideband driver only registers sidebands without tracking their active usage. To address this, sideband will now record its active usage when it creates/removes interrupters. In addition, a new api is introduced to provide a means for other dirvers to fetch sideband activity information on a USB host controller.

Add a driver for the Intel USBIO USB IO-expander used by the MIPI cameras on various new (Meteor Lake and later) Intel laptops. This is an USB bridge driver which adds auxbus child devices for the GPIO, I2C and SPI functions of the USBIO chip and which exports IO-functions for the drivers for the auxbus child devices to communicate with the USBIO device's firmware.
