Hi Tony, I have seen two small issues:
a) USB client mode works fine, except that on first plug in of the cable I see NOHZ warnings (which seem to be harmless):

It is the same on omap5uevm:

b) OTG mode detects cable plugin (extcon) and turns on power but dwc3 does not try to find the connected device

Same on omap5uevm (just power can be measured, not the bq24296 printk of course).
Any ideas how to fix / debug?
No idea what might be causing these, adding Roger to Cc.

Tony
