13  This is part of the device tree bindings for the S2MPG11 Power Management IC
14  (PMIC).
15
16  The Samsung S2MPG11 is a Power Management IC for mobile applications with buck
17  converters, various LDOs, power meters, NTC thermistor inputs, and additional
18  GPIO interfaces and typically complements an S2MPG10 PMIC in a main/sub
19  configuration as the sub-PMIC.

39      Phandle to the power supply for each buck rail of this PMIC. There is a
40      1:1 mapping of numbered supply to rail, e.g. vinb1s-supply supplies
41      buck1s. The remaining mapping is as follows
42        vinba - bucka

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