| This is part of the device tree bindings for the S2MPG11 Power Management IC |
| (PMIC). |
| |
| The Samsung S2MPG11 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. |

| description: |
| 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 |
| |
| "^vinl[1-6]s-supply$": |
| description: | |
| Phandle to the power supply for one or multiple LDO rails of this PMIC. |
| The mapping of supply to rail(s) is as follows |
| vinl1s - ldo1s, ldo2s |
| vinl2s - ldo8s, ldo9s |
| vinl3s - ldo3s, ldo5s, ldo7s, ldo15s |
