usb: mtu3: add SPL support

2026-08-09T11:26:42Z

MediaTek platforms may need the MTU3 controller before U-Boot proper is available, but the driver is currently selected and built only with the main U-Boot configuration symbols. Add an explicit SPL controller option with host and gadget modes. Make the driver build and its role checks phase-aware so each phase can select the MTU3 role it needs without coupling it to the U-Boot proper controller configuration. The upstream binding locates the xHCI child registers through the parent ranges property. Select SPL_OF_TRANSLATE for host mode so SPL can resolve that address before mapping it.

usb: mtu3: support the upstream devicetree binding

2026-08-09T11:26:42Z

The MTU3 glue driver expects a synthetic mediatek,ssusb child that combines the device and xHCI register windows. Upstream devicetrees instead put the device resources on the controller node and describe the xHCI window with a standard child node, so U-Boot cannot use an upstream topology. Switch to the upstream layout. The controller owns the shared resources and the device MAC, with the device register offsets relative to it as in Linux. The gadget role binds as a node-less internal device, while the host role binds to an enabled xHCI child and uses its own clocks, supplies and register window. dr_mode selects the role and defaults to otg, and the Kconfig choice constrains which role the build provides. The legacy child layout is rejected explicitly so its combined register window cannot be mistaken for the device MAC. Convert the in-tree MT8183 and MT8512 devicetrees in the same commit so neither platform is left without USB. MT8512 stays peripheral-only because its xHCI host interrupt is not documented and the mediatek,mtk-xhci binding requires it. Reviewed-by: Marek Vasut Signed-off-by: Carlo Caione

usb: mtu3: wait for TX FIFO to drain before disconnect

2026-08-02T20:13:19Z

Fastboot unregisters the USB gadget from the completion callback of its final OKAY response. MTU3 QMU can report that request complete while bytes remain in the endpoint TX FIFO. Disabling the USB function immediately can therefore disconnect the host before it receives the response. Before selecting the high-speed or SuperSpeed disconnect operation, poll the FIFO state of enabled IN endpoints that have no pending requests. Bound the wait to 1 ms. If a FIFO does not drain, reset its endpoint, force the disconnect, and propagate -ETIMEDOUT through the gadget pullup operation. Endpoints with pending requests are skipped so an ordinary disconnect does not wait for an active transfer.

usb: gadget: mtu3: Convert interrupt handling to usb_gadget_generic_ops

2024-07-05T12:08:35Z

Implement .handle_interrupts callback as a replacement for deprecated dm_usb_gadget_handle_interrupts() function. The new callback allows for each DM capable USB gadget controller driver to define its own IRQ handling implementation without colliding with other controller drivers.
