Library for USB PD

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

The library implements:

• A policy engine for each supported mode,
• the protocol layer, and
• the DevicePolicyManager trait, which allows a device user application to talk to the policy engine, and control it.

The library depends on the crate usbpd-traits, which provides traits for supporting USB PD PHYs.

Currently supported modes

• SPR and EPR sink mode
• Includes many helpers for requesting power sources, for example
  • the highest fixed voltage,
  • a specific fixed voltage and/or current, and
  • augmented PDOs (PPS or AVS).

Usage
