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"

USB-A ports charging mode default set to disabled.
If set, the USB-A charging mode is disabled.

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.
