Subject: [PATCH v2 1/3] dt-bindings: usb: introduce fsl,imx-dwc3
The i.MX USB glue and DWC3 core are closely coupled. Describe the i.MX
USB block in a single block will bring more benefits than a parent-
child relation. The new binding is a copy of fsl,imx8mp-dwc3.yaml with
the needed modifications.
Add the common compatible string "fsl,imx-dwc3" to indicate that the
flattened module should be selected. This compatible is also used by
"select" to inform the DeviceTree validator to apply this binding.
To avoid redefining all the platform-specific compatibles, "select" is
used to tell the DeviceTree validator which binding to use solely on the
generic compatible.
Mark fsl,imx8mp-dwc3 deprecated, to favor expressing future platforms
using the new combined binding.
