12description:
13  This is a device tree bindings for S2DOS family of Power Management IC (PMIC).
14
15  The S2DOS05 is a companion power management IC for the panel and touchscreen
16  in smart phones. Provides voltage regulators and
17  ADC for power/current measurements.
18
19  Regulator section has 4 LDO and 1 BUCK regulators and also
20  provides ELVDD, ELVSS, AVDD lines.
