+pwm regulator bindings
+
+Required properties:
+  - compatible: Should be "pwm-regulator"
+  - pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
+  - voltage-table: voltage and duty table, include 2 merbers in each set of
+    brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
+
+Any property defined as part of the core regulator binding defined in
+regulator.txt can also be used.
+
+Example:
+	pwm_regulator {
+		compatible = "pwm-regulator;
+		pwms = <&pwm1 0 1000000 0>;
+
+		voltage-table = <1114000 0>,
+				<1095000 10>,
+				<1076000 20>,
+				<1056000 30>,
+				<1036000 40>,
+				<1016000 50>;
+
+		regulator-always-on;
+		regulator-boot-on;
+		regulator-min-microvolt = <1016000>;
+		regulator-max-microvolt = <1114000>;
+		regulator-name = "vdd_logic";
+	};
