+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";
+ };
