The Samsung S2MPG11 PMIC is similar to the existing S2MPG10 PMIC supported by this binding, but still differs enough from it to justify a separate binding. 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'.

Phandle to the power supply for each buck rail of this PMIC. There is a
|
|
1:1 mapping of numbered supply to rail, e.g. vinb1s-supply supplies
|
|
buck1s. The remaining mapping is as follows

vinba - bucka

vinbb - buck boost

vinbd - buckd

The mapping of supply to rail(s) is as follows
