+Anatop Voltage regulators
+
+Required properties:
+- compatible: Must be "fsl,anatop-regulator"
+- anatop-reg-offset: Anatop MFD register offset
+- anatop-vol-bit-shift: Bit shift for the register
+- anatop-vol-bit-width: Number of bits used in the register
+- anatop-min-bit-val: Minimum value of this register
+- anatop-min-voltage: Minimum voltage of this regulator
+- anatop-max-voltage: Maximum voltage of this regulator
+
+Any property defined as part of the core regulator
+binding, defined in regulator.txt, can also be used.
+
+Example:
+
+        regulator-vddpu {
+                compatible = "fsl,anatop-regulator";
+                regulator-name = "vddpu";
+                regulator-min-microvolt = <725000>;
+                regulator-max-microvolt = <1300000>;
+                regulator-always-on;
+                anatop-reg-offset = <0x140>;
+                anatop-vol-bit-shift = <9>;
+                anatop-vol-bit-width = <5>;
+                anatop-min-bit-val = <1>;
+                anatop-min-voltage = <725000>;
+                anatop-max-voltage = <1300000>;
+        };
