dt-bindings: usb: qcom,snps-dwc3: Fix bindings for X1E80100

2025-10-13T07:38:04+00:00

Add the missing multiport controller binding to target list. Fix minItems for interrupt-names to avoid the following error on High Speed controller: usb@a200000: interrupt-names: ['dwc_usb3', 'pwr_event', 'dp_hs_phy_irq', 'dm_hs_phy_irq'] is too short Fixes: 6e762f7b8edc ("dt-bindings: usb: Introduce qcom,snps-dwc3") Cc: stable@vger.kernel.org Signed-off-by: Krishna Kurapati Reviewed-by: Krzysztof Kozlowski Signed-off-by: Greg Kroah-Hartman

dt-bindings: usb: switch: split out ports definition

2025-10-13T07:37:28+00:00

The ports definition currently defined in the usb-switch.yaml fits standards devices which are either recipient of altmode muxing and orientation switching events or an element of the USB Super Speed data lanes. This doesn't necessarely fit combo PHYs like the Qualcomm USB3/DP Combo which has a different ports representation. Move the ports definition to a separate usb-switch-ports.yaml and reference it next to the usb-switch.yaml, except for the Qualcomm USB3/DP Combo PHY bindings.

Merge patch series "Add SpacemiT K1 USB3.0 host controller support"

2025-09-17T10:38:35+00:00

Ze Huang says: The USB 3.0 controller found in the SpacemiT K1 SoC[1] supports both USB3.0 Host and USB2.0 Dual-Role Device (DRD). This controller is compatible with DesignWare Core USB 3 (DWC3) driver. However, constraints in the `snps,dwc3` bindings limit the ability to describe hardware-specific features in a clean and maintainable way. While `dwc3-of-simple` still serves as a glue layer for many platforms, it requires a split device tree node structure, which is less desirable in newer platforms. To promote a transition toward a flattened `dwc` node structure, this series introduces `dwc3-generic-plat`, building upon prior efforts that exposed the DWC3 core driver [2]. The device tree support for SpacemiT K1 will be submitted separately when the associated PHY driver is ready.

dt-bindings: usb: dwc3: add support for SpacemiT K1

2025-09-17T10:38:33+00:00

Add support for the USB 3.0 Dual-Role Device (DRD) controller embedded in the SpacemiT K1 SoC. The controller is based on the Synopsys DesignWare Core USB 3 (DWC3) IP, supporting USB3.0 host mode and USB 2.0 DRD mode.

dt-bindings: usb: usb251xb: support usage case without I2C control

2025-09-06T13:23:29+00:00

Currently, the usb251xb assumes i2c control, but from HW point of view, the hub supports usage case without any i2c control, I.E we only want the gpio controls, for example the following dt node: usb-hub { compatible = "microchip,usb2512b"; reset-gpios = <&porta 8 GPIO_ACTIVE_LOW>; }; Modify the dt-binding of usb2512b to support this usage case, and add the usage example to the examples section.
