	  Enable this if the board can enable VBUS discharge (eg. through a
	  GPIO-controlled discharge circuit, or through port controller
	  registers) to discharge VBUS rapidly on disconnect

config PLATFORM_EC_USB_PD_DISCHARGE_TCPC
	bool "Discharge circuit is provided by the TCPC"
	help
	  Enable this if the discharge circuit is provided by Power-Delivery
	  resistors on the USB Type-C Port Controller (TCPC).

config PLATFORM_EC_USB_PD_DISCHARGE_PPC
	bool "Discharge circuit is provided by the PPC"
	help
	  Enable this if the discharge circuit is using Power Delivery
	  resistors on the Power Path Controller.
