It is a Power Management IC for mobile applications with buck converters, various LDOs, power meters, NTC thermistor inputs, and additional GPIO interfaces and typically complements an S2MPG10 PMIC in a main/sub configuration as the sub-PMIC. Like S2MPG10, communication is via the Samsung ACPM firmware and it therefore needs to be a child of the ACPM firmware node. Add the PMIC, the regulators node, and the supply inputs of the regulator rails, with the supply names matching the datasheet. Note: S2MPG11 is typically used as the sub-PMIC together with an S2MPG10 PMIC in a main/sub configuration, hence the datasheet and the binding both suffix the supplies with an 's'.
