Cover letter [PATCH 0/2] AM437x: USB DWC3: save power during system sleep

Hi,

This series add support to DWC3 core to conserve power during system sleep by setting the USB DRVVBUS line to a lower power consuming state.

Tested to make sure USB host and device works on AM437x with v4.2. Tested for power savings on v4.1 kernel where there is an implementation of suspend- to-RAM for AM437x available.
