+
+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.
