class SinkPolicyEngineStateMachine

Defined at line 53 of file ../../src/devices/power/drivers/fusb302/pd-sink-state-machine.h

Implements the USB PD Sink Policy Engine state machine.

usbpd3.1 8.3.3 "State Diagrams", especially 8.3.3.3 "Policy Engine Sink Port

State Diagram"

Public Methods

void Reset ()

Called when the Type C port state changes.

Defined at line 39 of file ../../src/devices/power/drivers/fusb302/pd-sink-state-machine.cc

void DidReceiveSoftReset ()

Called when the driver reports the receipt of a Soft Reset message.

This is a separate method to facilitate interacting with hardware that

reports Soft Reset receipt via dedicated signals, instead of simply

bubbling the PD message's bytes up to the driver.

Drivers must always report Soft Reset receipt via this method. Soft Reset

must not also be reported as received PD messages.

void SinkPolicyEngineStateMachine (usb_pd::SinkPolicy & policy, Fusb302 & device, inspect::Node inspect_root)

`policy` and `device` must remain alive throughout the new instance's

lifetime.

Diagram" and Section 8.3.3.4.2 "SOP Sink Port Soft Reset and Protocol Error

State Diagram" of the USB PD spec.
