-	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 dedine 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.

-config PLATFORM_EC_BATTERY_SMART

-	help
-	  Many batteries support the Smart Battery Specification and therefore

-	  buck-boost, narrow-output-voltage charger supporting an input voltage
-	  of 3.2-23.4V and output of 2.4 V-13.8V. It provides an I2C interace
