[PATCH v2 0/2] usb: dwc3: Add dual-role support using OTG core

[Roger Quadros <rogerq@ti.com>]

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.
