+* Dialog DA9052/53 Power Management Integrated Circuit (PMIC)
+
+Required properties:
+- compatible : Should be "dlg,da9052", "dlg,da9053-aa",
+			 "dlg,da9053-ab", or "dlg,da9053-bb"
+
+Sub-nodes:
+- regulators : Contain the regulator nodes. The DA9052/53 regulators are
+  bound using their names as listed below:
+
+    buck0     : regulator BUCK0
+    buck1     : regulator BUCK1
+    buck2     : regulator BUCK2
+    buck3     : regulator BUCK3

+    ldo12     : regulator LDO12
