Hi guys,

The software nodes support node hierarchy. By using them with fusb302
we can add a separate fwnode also for the USB connector as a child of
fusb302. We can then use the "standard" USB connector device
properties with the connector node, and stop using the deprecated
fusb302 specific properties.

Since the goal is to ultimately move to the software node API from the
old device property API, converting also max17047 in this series.

If you test this now (before v5.1-rc1 is out), then the series depends
Greg's latest usb-next:

and on a patch in Rafael's latest linux-next branch:

Interesting series, I like the direction this is heading in.

Question, I currently have this hack to test DP over Type-C on the
GPD-pocket / GPD-win:

Do this properly we need to add alt-modes support for usb-c-connector nodes to:
Documentation/devicetree/bindings/connector/usb-connector.txt

Do you have any ideas for what the binding this should look like, we need to
specify a svid, mode and vdo tripple in this case. Maybe use an u32 array
with 3, 6, 9, ... entries depending on how much alt-modes the fwnode needs to
specify ?
