config PLATFORM_EC_BATTERY

bool "Support batteries"
|
||||
help
|
||||
Enables battery support on the board. Requires selection of a battery
|
||||
and a charger IC.
|
||||
|
||||
If using I2C batteries, you must define I2C_PORT_BATTERY in your
|
||||
board's i2c_map.h file so that the EC code will know which I2C
|
||||
port the battery is on.

smart battery option.

|

help
|

Many batteries support the Smart Battery Specification and therefore
|
||||
have common registers which can be accessed to control and monitor
|
||||
the battery.

be selected.

depends on PLATFORM_EC_I2C
|

help
|

Enables a driver for the ISL9241 VCD Battery Charger. This is a
|
||||
digitally-configurable, buck-boost battery charger that can support
|
||||
both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck Boost
|
||||
(HPBB/Bypass) charging and switch between the modes under firmware
|
||||
control. It supports an input voltage range of 3.9-23.4V and output
|
||||
of 3.9-18.3V. It provides an I2C interace for configuration.
