if PLATFORM_EC_USBC
config PLATFORM_EC_USB_CHARGER
bool "Support charging from a USB-C port"
default y
help
This enables common BC1.2 (Battery-Charging Specification Rev1.2)
charger-detection routines. With this is possible to negotiate a
power contract with an attached battery charger and use this to
charge the device's battery.
if PLATFORM_EC_USB_CHARGER
config PLATFORM_EC_USB_CHARGER_SINGLE_TASK
bool "Run all charger code in a single task"
default y
help
Run all USB charger code in a single task rather than a task per port.
config PLATFORM_EC_BC12_DETECT_DATA_ROLE_TRIGGER
bool
help
This is a helper symbol that indicates the BC1.2 chip needs to be
triggered on data role swaps in addition to VBUS changes.
config PLATFORM_EC_BC12_DETECT_PI3USB9201
bool "Enable support for Pericom PI3USB9201"
select PLATFORM_EC_BC12_DETECT_DATA_ROLE_TRIGGER
help
This is a Dual-Role USB Charging-Type Detector. It can operate in
host or client mode. It supports Battery Charging Specification, rev
1.2 (BC1.2) with Standard/Charging/Dedicated downstream port
(SDP/CDP/DCP) advertisement when in host mode. In client mode it
starts BC1.2 detection to detect the attached host type. It provides
an I2C interface to report detection results.
config PLATFORM_EC_BC12_DETECT_MT6360
bool "MediaTek MT6360P PMIC"
help
This PMIC includes a battery charger with an On-The-Go (OTG) output
range of 4.85 to 5.825V. It provides integrated ADCs for system
monitoring. The MT6360 also supports USB Power Delivery 3.0 with
Dual-Role, with host or client mode. It supports alternate mode as
well as VCONN with programmable over-current protection (OCP).
config PLATFORM_EC_MT6360_BC12_GPIO
bool "USB-PHY connection is controlled by a GPIO"
depends on PLATFORM_EC_BC12_DETECT_MT6360
help
If enabled, the MT6360 USB-PHY connection is controlled by
a GPIO: GPIO_BC12_DET_EN. Assert GPIO_BC12_DET_EN to detect a BC1.2
device, and deassert GPIO_BC12_DET_EN to mux the USB-PHY back.
config PLATFORM_EC_BC12_SINGLE_DRIVER
bool "Only support a single BC12 driver"
default y
help
Enable this if the board only needs one BC12 driver. This includes
the case that has multiple chips that use the same driver.
If undefined, the board should define a bc12_ports[] array which
associates each port to its bc12 driver:
struct bc12_config bc12_ports[CONFIG_USB_PD_PORT_MAX_COUNT] = {
{ .drv = &xxx_drv },
{ .drv = &yyy_drv },
};
