Hi Felipe,
I have made otg mode work on the omap5-uevm with help from Roger
and now I wonder how to read the interface status for GUI display.
On omap3/twl4030 systems we can simply read
/sys/bus/platform/devices/musb-hdrc.0.auto/mode
and get reports e.g. "b_peripheral", "a_host", "b_idle" etc. which can easily
be translated into icons for GUI display.
We have not found a similar attribute for dwc3 (except part of this information
in
/sys/kernel/debug/4a030000.dwc3
but mounting debugfs for GUI purposes isn't a good idea).
So do you think it is possible to provide such information to
/sys/devices/platform/44000000.ocp/4a020000.omap_dwc3/4a030000.dwc3?
BR,
Nikolaus

This question is not specific to omap5.
What is your opinion? If you think it is OK, I can provide a patch for it.

sounds like this should be part of DRD/OTG core, no?
