dt-bindings: usb: cdns3: Add cdns,cdnsp compatible string

2026-05-22T09:36:05+00:00

Introduce a new generic fallback compatible string 'cdns,cdnsp' for Cadence USBSSP controllers to support hardware configurations where the Dual-Role Device (DRD) register block is missing or inaccessible. Following the maintainer's feedback, avoid generic property-like naming (such as "-no-drd") and use a clean generic fallback. To keep the schema resource-driven and strictly validated, define a two-string compatible matrix using an empty schema ({}) wildcard. This allows future vendor SoC compatibles to be prepended while safely falling back to the 2-resource USBSSP configuration. When 'cdns,cdnsp' is matched: - The 'otg' register and interrupt resources are not required. - The 'reg' and 'interrupts' properties are restricted to 2 items (host and device). - 'dr_mode' must be explicitly set to either 'host' or 'peripheral'. The standard 'cdns,usb3' compatible remains unchanged, maintaining backward compatibility by requiring all 3 resource sets (otg, host, dev).

dt-bindings: usb: qcom,pmic-typec: deprecate device-specific VBUS

2026-05-22T09:35:43+00:00

The Qualcomm PMIC Type-C devices historically provided their own way of specifying the VBUS regulator, via the device's vdd-vbus-supply node. This is not ideal as the VBUS is supplied to the connector and not to the Type-C block in the PMIC. Deprecate this property in favour of the standard way of specifying it (via the connector's vbus-supply property).

dt-bindings: usb: qcom,pmic-typec: Drop redundant port

2026-05-22T09:35:31+00:00

The binding defines both "port" and "connector" properties, where the "port" is claimed to be for "data-role switching messages". There is no such dedicated data port for this device and role switching is part of connector ports - the port going to the USB controller. The driver does not use the "port" property and there is no upstream DTS which would have it. It looks like it's left-over of early versions of this patchset and is completely redundant now, so let's drop it.

dt-bindings: usb: ci-hdrc-usb2: allow up to 3 clocks for qcom,ci-hdrc

2026-05-22T09:35:03+00:00

Some Qualcomm SoCs such as apq8064 and msm8960 require a third "fs" clock in addition to "iface" and "core", needed to propagate resets through the controller and wrapper logic. Later SoCs such as msm8974 dropped this requirement and only use two clocks. Note that the existing apq8064 and msm8960 DTS files currently specify the "iface" and "core" clocks in reverse order compared to most newer SoCs DTS, which causes dtbs_check warnings for these older SoCs. The dependent patch series will fix that clock ordering.

dt-bindings: usb: Fix EIC7700 USB reset's issue

2026-05-22T09:13:19+00:00

The EIC7700 USB requires a USB PHY reset operation; otherwise, the USB will not work. The reason why the USB driver that was applied can work properly is that the USB PHY has already been reset in ESWIN's U-Boot. However, the proper functioning of the USB driver should not be dependent on the bootloader. Therefore, it is necessary to incorporate the USB PHY reset signal into the DT bindings. This patch does not introduce any backward incompatibility since the dts is not upstream yet. As array of reset operations are used in the driver, no modifications to the USB controller driver are needed.

dt-bindings: usb: ti,omap4-musb: Drop duplicate 'usb-phy' property constraints

2026-05-22T09:12:57+00:00

The deprecated 'usb-phy' property is documented already in usb.yaml and doesn't need a type definition here. It just needs constraints on how many entries there are. As this is a host controller, reference usb-hcd.yaml which then references usb.yaml.
