I see these options (ordered by my preference):

1: Vinod merges everything; the USB side is mostly a new driver
   and thus there is not much conflict potential

2: Vinod provides an immutable branch with the first two patches,
   USB tree merges the immutable branch and the remaining series.

3: Everything is merged through USB; this would block the final
   cleanup for USBDP from being applied for yet another cycle.

4: Vinod merges patches 1+2, USB patches are merged one cycle
   later and final USBDP patches are merged two cycles later.

P.S.: I will have to send another version for the correct Sashiko
feedback on the DWC3 side.
