Library for USB PD

Modeled after the Universal Serial Bus Power Delivery Specification: USB PD R3.2 v1.1 (2024/10).

The library therefore implements:

• A policy engine for each supported mode,
• the protocol layer, and
• traits for interfacing a user application.

These traits are

• the Driver that provides methods to talk to the device's PHY, and
• the DevicePolicyManager, which allows a device to talk to the policy engine, and control it.

Currently supported modes

• SPR Sink with helpers for requesting
  • A fixed supply
  • A Programmable Power Supply (PPS)
