| description: |
| This is a device tree bindings for S2DOS family of Power Management IC (PMIC). |
| |
| The S2DOS05 is a companion power management IC for the panel and touchscreen |
| in smart phones. Provides voltage regulators and |
| ADC for power/current measurements. |
| |
| Regulator section has 4 LDO and 1 BUCK regulators and also |
| provides ELVDD, ELVSS, AVDD lines. |
