We've performed some work on the Generic USB HCD, xHCI and DWC USB3 DT bindings in the framework of the Baikal-T1 SoC support integration into the kernel. This patchset is a result of that work. First of all we moved the generic USB properties from the legacy text bindings to the USB DT schema. The properties have been distributed between three DT schemas dedicated for particular types of USB controllers: Generic USB controller properties (like node-naming, phys, maximum-speed, etc), Generic USB Host Controller bindings (companion and TPL support), Dual-Role USB Controller (OTG revision, DR mode, HNP/SRP/ADP protocols, etc). So the USB controllers DT bindings from now can validate the nodes against a generic USB-controller schema suitable for the controller functionality. Secondly we converted generic USB xHCI text bindings file into the DT schema. It had to be split up into two bindings: DT schema with generic xHCI properties and a generic xHCI device DT schema. The later will be used to validate the pure xHCI-based nodes, while the former can be utilized by some vendor-specific versions of xHCI. Thirdly, what was primarily intended to be done for Baikal-T1 SoC USB we converted the legacy text-based DWC USB3 bindings to DT schema and altered the result a bit so it would be more coherent with what actually controller and its driver support. Since we've now got the DWC USB3 DT schema, we made it used to validate the sub-nodes of the Qualcom, TI and Amlogic DWC3 DT nodes.

Link: https://lore.kernel.org/linux-usb/20201020112101.19077-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx Changelog v4: - Get the patch [PATCH 11/17] dt-bindings: usb: dwc3: Add synopsys,dwc3 compatible string back, since we can't discard the deprecated prefix from the driver. - Discard the block scalar style modifier "|" from the interrupts property description. - Split the generic USB controller properties into three schemas: Generic USB controllers, USB Host controllers and USB OTG controllers.
