Hi Vivek,

which is the relationship of your patch and this commit:

e1d9149e8389f1690cdd4e4056766dd26488a0fe
arm64: dts: rockchip: Fix USB3 Type-C on rk3399-sapphire

with respect to this other commit:

c09b73cfac2a9317f1104169045c519c6021aa1d
usb: dwc3: don't set gadget->is_otg flag

?

I did not test reverting e1d9149e since c09b73cf was applied.

Regards,
  Vicenç.
