Hi all,
I recently submitted a patch to fix the support for the DWC3 controller on the imx8mq which, unlike most DWC3 implementation, doesn't use a top glue node with child DWC3 nodes. Instead it has the DWC3 node directly on the main bus.
Angus Ainslie then asked why this patch was needed as he had submitted the original support for the imx8mq. Looking into the issue it turned out that Angus patch basically let the driver use the `port` subnodes, which are there to define the connection to a type C connector, as DWC3 nodes. As the board I'm working on has no type C connecor, hence no `port` subnodes the driver just did nothing in my case.
This new series replace my previous patch (usb: dwc3-generic: Fix the iMX8MQ support). It starts by reverting Angus patch as it was not following the DT binding and then add support for generic DWC3 without glue node. This fix the imx8mq case and might add support for a few other SoC at the same time.
