Thanks for the review Siddharth. Could you or someone familiar with the current USB tooling update the documentation for the DWC3 [1]? I'm not sure if it was never correctly imported from the processor wiki or what, but it appears there a sections missing and the content present appears disjointed. A lot of it can be reduced to links to the upstream DWC3 docs [2] and linked gadget configfs. At the moment the only thing that even mentions gadget configfs is the AM62_DWC3 document, and it only does so because of a kconfig code snippet.
