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. All of these have been in linux-next for a while" * tag 'usb-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (132 commits) usb: vhci-hcd: Prevent suspending virtually attached devices USB: serial: option: add SIMCom 8230C compositions thunderbolt: Fix use-after-free in tb_dp_dprx_work usb: xhci: align PORTSC trace with one-based port numbering usb: xhci: correct indentation for PORTSC tracing function usb: xhci: improve TR Dequeue Pointer mask usb: xhci-pci: add support for hosts with zero USB3 ports usb: xhci: Update a comment about Stop Endpoint retries Revert "usb: xhci: Avoid Stop Endpoint retry loop if the endpoint seems Running" usb: gadget: f_rndis: Refactor bind path to use __free() usb: gadget: f_ecm: Refactor bind path to use __free() usb: gadget: f_acm: Refactor bind path to use __free() usb: gadget: f_ncm: Refactor bind path to use __free() usb: gadget: Introduce free_usb_request helper usb: gadget: Store endpoint pointer in usb_request usb: host: xhci-rcar: Add Renesas RZ/G3E USB3 Host driver support usb: host: xhci-plat: Add .post_resume_quirk for struct xhci_plat_priv usb: host: xhci-rcar: Move R-Car reg definitions dt-bindings: usb: Document Renesas RZ/G3E USB3HOST usb: gadget: f_fs: Fix epfile null pointer access after ep enable. ...

Pull changes from the immutable branch between MFD, GPIO, Input, Pinctrl and PWM trees containing the GPIO driver for max7360.

gpio: max7360: Add MAX7360 gpio support

2025-09-16T14:24:48+00:00

Add driver for Maxim Integrated MAX7360 GPIO/GPO controller. Two sets of GPIOs are provided by the device: - Up to 8 GPIOs, shared with the PWM and rotary encoder functionalities. These GPIOs also provide interrupts on input changes. - Up to 6 GPOs, on unused keypad columns pins.

gpiolib: make legacy interfaces optional

The traditional interfaces are only used on a small number of ancient boards. Make these optional now so they can be disabled by default.

gpio: Add new gpio-macsmc driver for Apple Macs

2025-07-24T08:47:33+00:00

This driver implements the GPIO service on top of the SMC framework on Apple Mac machines. In particular, these are the GPIOs present in the PMU IC which are used to control power to certain on-board devices. Although the underlying hardware supports various pin config settings (input/output, open drain, etc.), this driver does not implement that functionality and leaves it up to the firmware to configure things properly. We also don't yet support interrupts/events. This is sufficient for device power control, which is the only thing we need to support at this point. More features will be implemented when needed. To our knowledge, only Apple Silicon Macs implement this SMC feature.

gpiolib: acpi: Move quirks to a separate file
