This patch set adds sink side support for the PPS feature introduced in the USB PD 3.0 specification.
The source PPS supply is represented using the Power Supply framework to provide access and control APIs for dealing with it's operating voltage and current, and switching between a standard PDO and PPS APDO operation. During standard PDO operation the voltage and current is read-only, but for APDO PPS these are writable as well to allow for control. It should be noted that the keepalive for PPS is not handled within TCPM. The expectation is that the external user will be required to ensure re-requests occur regularly to ensure PPS remains and the source does not hard reset. So with all of that covered, please feel free to rip this apart as you see fit. Note: Code changes are based on linux-next tag 'next-20171017' to pick up the move out of staging of TCPM related code.
