Defined at line 95 of file ../../src/devices/power/drivers/fusb302/usb-pd-message-objects.h

Well-regulated power supply that maintains a fixed voltage.

See `PowerData` for a general description of the PDO (Power Data Object)

representation.

Sink requirements for a well-regulated power supply are expressed via

`SinkFixedPowerSupplyData` instances.

Public Methods

usb_pd::FixedPowerSupplyData & set_supports_dual_role_power (typename std::remove_reference_t<decltype(bits_)> val)

Indicates support for the PR_Swap message.

Only used on the first PDO in a Source_Capabilities message.

typename std::remove_reference_t<decltype(bits_)> supports_dual_role_power ()

Indicates support for the PR_Swap message.

Only used on the first PDO in a Source_Capabilities message.

typename std::remove_reference_t<decltype(bits_)> requires_usb_suspend ()

Indicates whether the Sink must follow USB suspend rules.

usbpd3.1 names this field USB Suspend Supported, but it conveys

requirements for the Sink. The requirements apply after a PD Contract is

negotiated. 6.4.1.2.2 "USB Suspend Supported", states that a peripheral may

draw up to 25 mW (pSnkSusp) and a hub may draw up to 125 mW (pHubSusp)

during suspend, and defers to usb2, usb3.2 and usb4.

Only used on the first PDO in a Source_Capabilities message.
