	help
	  Enable this to support various USB Type-C features chosen by the
	  options below. USB-C is widely used on modern Chromebooks and the EC's
	  role is to negotiate power contracts (for sourcing or sinking power
	  over USB). The EC is also responsible for discovering the capabilities
	  of attached USB-C partners and enabling alternate operational modes,
	  including Display Port, Thunderbolt, and USB4.

config PLATFORM_EC_CHARGER_INPUT_CURRENT
	int "Charger input current in mA"
	depends on PLATFORM_EC_CHARGE_MANAGER
	default 512
	help
	  This is the default input current for the board in mA.  Many boards
	  also use this as the least maximum input current during transients.

	  This value should depend on external power adapter, designed charging
	  voltage, and the maximum power of the running system. For type-C
	  chargers, this should be set to 512 mA in order to not brown-out
	  low-current USB charge ports in accordance with USB-PD r3.0 Sec. 7.3

config PLATFORM_EC_USBC_OCP
	bool
	help
	  USB-C overcurrent protection: Enable this to detect when a connected
	  USB-C partner draws too much power from the Chromebook and
	  automatically shut off power to the USB-C partner.

	  This should be enabled by drivers which can detect over-current. It
	  cannot be set otherwise, even in prj.conf

config PLATFORM_EC_USB_PID
	hex "USB Product ID"
	help
	  Each platform (e.g. baseboard set) should have a single VID/PID
	  combination. If there is a big enough change within a platform,
	  then we can differentiate USB topologies by varying the hardware
	  version field in the Sink and Source Capabilities Extended messages.

	  To reserve a new PID within Google, use go/usb and see
	  http://google3/hardware/standards/usb

config PLATFORM_EC_USB_BCD_DEV
	hex "USB Device ID"
	default 0
	help
	  This specifies the USB device version, reported by board when acting
	  as the upstream facing port (UFP). This is a 16-bit unsigned integer
	  and should be set to a version number relevant to the release version
	  of the product.

config PLATFORM_EC_USB_VID
	hex "USB Vendor ID"
	default 0x18d1
	help
	  This specifies the USB vendor ID used for boards which expose a
	  USB endpont when the port is in UFP mode. The default value is
	  set to Google's assigned VID and typically would not need to be
	  changed. But, in certain cases this may need to be changed to
	  match an OEM's vendor ID.

config PLATFORM_EC_USB_MS_EXTENDED_COMPAT_ID_DESCRIPTOR
	bool "USB MS Extended Compat ID Feature Descriptor"
	help
	  This enables USB-EP to contain a MS Windows USB string descriptor
	  which is then used by MS Windows to request a Extended Compatible
	  ID Feature descriptor so that Windows will know to load its WINUSB
	  driver.

config PLATFORM_EC_USB_PD_TCPC_LOW_POWER
	bool "Allow Type-C Port Controller to enter low-power mode"
	default y
	help
	  Allows entry to a low power mode when the USB port is idle.
	  When enabled, an enter_low_power_mode member is present in tcpm_drv
	  and should be set to a function that selects that mode, such as
	  tcpci_enter_low_power_mode() for TCPCI-compatible TCPCs.

config PLATFORM_EC_USB_PD_TCPC_LPM_EXIT_DEBOUNCE_US
	int "Debounce delay when exiting low-power mode (uS)"
	depends on PLATFORM_EC_USB_PD_TCPC_LOW_POWER
	default 25000
	help
	  Some TCPCs need additional time following a VBUS change to internally
	  debounce the CC line status and update the CC_STATUS register. This
	  is the delay in microseconds to allow before checking the CC line
	  status in the EC.

config PLATFORM_EC_USB_PD_TCPC_VCONN
	bool "If VCONN is enabled, the TCPC will provide VCONN"
	default y if !PLATFORM_EC_USBC_PPC_SYV682X
	default y if PLATFORM_EC_USB_PD_TCPM_ITE_ON_CHIP
	default y if PLATFORM_EC_USBC_PPC_SYV682X_NO_CC
	help
	  Source USB Type-C connector voltage (VCONN) from the Type-C Port
	  Controller (TCPC), and also the Power Path Controller (PPC) if
	  present. Some TCPC/PPC can't handle 5V on its host-side CC pins, so
          disable this config in those cases.

config PLATFORM_EC_CONSOLE_CMD_PPC_DUMP
	bool "Console command: ppc_dump"
	depends on PLATFORM_EC_USBC_PPC
	default y
	help
	  Allows dumping of the Power Path Controller (PPC) state, which is
	  basically a list of registers and their values. The actual dump
	  function is driver-specific (the reg_dump member of ppc_drv). By
	  reference to the datasheet for the part this can help you figure out
	  what is going on.

config PLATFORM_EC_USB_PD_TCPM_DRIVER_IT83XX
	bool "Enable IT83XX driver"
	depends on PLATFORM_EC_USB_PD_TCPM_ITE_ON_CHIP
	help
	  Enable a driver for the ITE IT83XX on-chip UBB Type-C Port Manager.
	  This supports up to two USB Type-C ports with Dual Role function
	  (provider and consumer) and Fast Role Swap detection.

config PLATFORM_EC_USB_PD_TCPM_DRIVER_IT8XXX2
	bool "Enable IT8XXX2 driver"
	depends on PLATFORM_EC_USB_PD_TCPM_ITE_ON_CHIP
	help
	  Enable a driver for the ITE IT8XXX2 on-chip UBB Type-C Port Manager.
	  This supports up to two USB Type-C ports with Dual Role function
	  (provider and consumer) and Fast Role Swap detection.

config PLATFORM_EC_USB_PD_PULLUP
	int "Default source Rp value"
	default 1
	help
	  Default pull-up value on the USB-C ports when they are used as source.
	  Valid values are 0 (USB default current), 1 (1.5A), and 2 (3.0A). See
	  enum tcpc_rp_value.

config PLATFORM_EC_USB_PD_ONLY_FIXED_PDOS
	bool "Only support FIXED type PDOs"
	help
	  Ignore all non-fixed PDOs received from a src_caps message. Enable
	  this for boards (like servo_v4) which only support FIXED PDO types.
