+ constant-charge-voltage-max-microvolt,
+ voltage-max-design-microvolt,

+- rockchip,resistor-sense-micro-ohms: Value in microohms of the battery sense
+ resistor. The PMIC only supports values
+ of either 10000 or 20000. This value is
+ used by the driver to set the correct
+ divisor value to translate ADC readings
+ into the proper units of measure.
+- rockchip,sleep-enter-current-microamp: Value in microamps of the sleep enter
+ current for the charger. Value is used

+ threshold.
+- rockchip,sleep-filter-current-microamp: Value in microamps of the sleep
+ filter current for the charger.
