/**
 * Configuration required to write out a Type-C Connector ACPI object.
 *
 * @power_role: DUAL if device supports being both a source and a sink, otherwise choose
 *      the device's default power role
 * @try_power_role: SINK if device supports Try.SNK, SOURCE if device supports Try.SRC,
 *      otherwise choose NONE
 * @data_role: Choose DUAL if device can alternate between UFP (host) & DFP (device),
 *      otherwise specify UFP or DFP.
 * @usb2_port: Reference to the ACPI device that represents the USB2 signals
 * @usb3_port: Reference to the ACPI device that represents the USB3 signals
 * @usb4_port: Reference to the ACPI device that represents the USB4 signals
 * @orientation_switch: Reference to the ACPI device that controls the switching of
 *      the orientation/polarity for Data and SBU lines.
 * @usb_role_switch: Reference to the ACPI device that can select the USB role,
 *      host or device, for the USB port
 * @mode_switch: Reference to the ACPI device that controls routing of data lines to
 *      various endpoints (xHCI, DP, etc.) on the SoC.
 * @pld: Reference to PLD information.
