+
+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.
