Thanks for digging into this!

I have successfully used automatic role-switching (even switching 
between USB2 gadget and USB3+DP mostly worked fine) but I do remember 
manual sysfs switching causing more issues..

Would be great to see no more dr_mode = "host" upstream. Though I 
vaguely remember some objections related to booting from USB (?)
