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.
