menuconfig PLATFORM_EC_USBA
	bool "USB Type-A support"
	default y
	depends on DT_HAS_CROS_EC_USBA_PORT_ENABLE_PINS_ENABLED
	help
	  Enable USB Type A ports

	  To use this your board code must provide a usb_port_enable[] array
	  with the GPIOs to use for each port, which may be specified via
	  device tree with "cros-ec,usba-port-enable-pins" nodes. This
	  implements the EC_CMD_USB_CHARGE_SET_MODE host command and provides
	  a 'usbchargemode' console command.

if PLATFORM_EC_USBA

config PLATFORM_EC_USB_PORT_ENABLE_DYNAMIC
	bool "USB Type-A dynamic port count"
	help
	  Allow the USB Type-A port array to be dynamically
	  modified by board specific code.

	  This allows boards to selectively disable any of the
	  USB Type-A ports by setting the enable entry to
	  a negative value.

choice PLATFORM_EC_USBA_PORT_POWER_TYPE
	prompt "Port power control mode"
	default PLATFORM_EC_USB_PORT_POWER_DUMB

config PLATFORM_EC_USB_PORT_POWER_DUMB
	bool "Dumb"
	help
	  USB-A ports are controlled with a single GPIO each, where turning it
	  on enables the port and turning it off disables the port.

config PLATFORM_EC_USB_PORT_POWER_SMART
	bool "Smart"
	help
	  USB-A ports are controlled via a smart switch, which allows dynamic
	  selection of port current limits and BC1.2 charging modes as well
	  as a signal to enable or disable power to the port.

endchoice

config PLATFORM_EC_USB_PORT_POWER_DUMB_CUSTOM_HOOK
	bool "Disable default dumb port power hooks"
	depends on PLATFORM_EC_USB_PORT_POWER_DUMB
	help
	  Enable this if your board does not want to use the default S3 hooks
	  from USB_PORT_POWER_DUMB.

if PLATFORM_EC_USB_PORT_POWER_SMART

config PLATFORM_EC_USB_PORT_POWER_SMART_CDP_SDP_ONLY
	bool "CDP/SDP mode only"
	help
	  Enable this if the USB-A smart switch mode selection is fixed and
	  the only control is for CDP or SDP mode via current limit selection.
	  Only the ILIM GPIOs will be controlled, not CTL*.

config PLATFORM_EC_USB_PORT_POWER_SMART_SIMPLE
	bool "Shared 2-wire control"
	depends on !PLATFORM_EC_USB_PORT_POWER_SMART_CDP_SDP_ONLY
	select PLATFORM_EC_USB_PORT_POWER_SMART_INVERTED
	help
	  Enable this if the EC has a single GPIO tied to the CTL1 line and a
	  single ILIM signal, each shared with every USB-A port. This implies
	  that only these lines can be manipulated (CTL2 and CTL3 are fixed in
	  hardware) and that any configuration to one port will also adjust the
	  others.

	  If disabled, the EC controls all of ILIM and CTL1 through CTL3 for
	  every port individually.

config PLATFORM_EC_USB_PORT_POWER_SMART_INVERTED
	bool "ILIM signal polarity is inverted"
	help
	  Select this option if the ILIM signal going to the port controller(s)
	  is inverted, meaning a low value indicates a high current limit and a
	  high value requests a low current limit.

choice PLATFORM_EC_USBA_PORT_POWER_SMART_DEFAULT_MODE
	prompt "Port power smart charging default mode"
	default PLATFORM_EC_USB_PORT_POWER_SMART_DEFAULT_SDP

config PLATFORM_EC_USB_PORT_POWER_SMART_DEFAULT_DISABLED
	bool "Disabled"
	help
	  USB-A ports charging mode default set to disabled.
	  If set, the USB-A charging mode is disabled.

config PLATFORM_EC_USB_PORT_POWER_SMART_DEFAULT_SDP
	bool "SDP"
	help
	  USB-A ports charging mode default set to Standard Downstream
	  Port, USB 2.0 mode.

config PLATFORM_EC_USB_PORT_POWER_SMART_DEFAULT_CDP
	bool "CDP"
	help
	  USB-A ports charging mode default set to Charging Downstream
	  Port, BC 1.2.
