Hi Felipe, Some platforms (e.g. TI's AM437x) don't have USB ID pin state available over GPIO/extcon but need to rely on the DWC3 core's OTG block to get the ID pin state instead.
This series implements simple dual-role functionality using DWC3's OTG block. Debugfs 'mode' override is also functional so user can switch between "otg", "host" or "device" modes for debug. Although system suspend/resume isn't working yet in mainline for AM437x, I've tested this series for system suspend/resume using a local tree.
