+AXP20x and AXP22x battery power supply
+
+Required Properties:
+ - compatible, one of:
+ "x-powers,axp209-battery-power-supply"
+ "x-powers,axp221-battery-power-supply"
+
+This node is a subnode of the axp20x/axp22x PMIC.
+
+The AXP20X and AXP22X can read the battery voltage, charge and discharge
+currents of the battery by reading ADC channels from the AXP20X/AXP22X
+ADC.
+
+Example:
+
+&axp209 {
+ battery_power_supply: battery-power-supply {
+ compatible = "x-powers,axp209-battery-power-supply";
+ }
+};
