I also have a question for host and device mode switch at DWC3
controller with on PCI bus. I saw omap glue get extcon cable state to
identify ID pin, am I right?
if (extcon_get_cable_state(edev, "USB-HOST") == true)
dwc3_omap_set_mailbox(omap, OMAP_DWC3_ID_GROUND);
But I don't find any similar identification on PCI glue. So how PCI
glue execute this action?
Thanks,
Rui
