It can be controlled through an I2C interface. +The RN5T618/RC5T619 provides additionally a Li-ion battery charger, +fuel gauge, and an ADC. +The RC5T619 additionnally includes USB charger detection and an RTC. + +Required properties: + - compatible: must be one of + "ricoh,rn5t567" + "ricoh,rn5t618" + "ricoh,rc5t619" + - reg: the I2C slave address of the device + +Sub-nodes: + - regulators: the node is required if the regulator functionality is + needed.
