+* Maxim MAX8973 Voltage Regulator
+
+Required properties:
+
+- compatible: must be one of following:
+ "maxim,max8973"
+ "maxim,max77621".
+- reg: the i2c slave address of the regulator. It should be 0x1b.
+
+Any standard regulator properties can be used to configure the single max8973
+DCDC.
+
+Optional properties:
+
+-maxim,externally-enable: boolean, externally control the regulator output
+ enable/disable.
+-maxim,enable-gpio: GPIO for enable control. If the valid GPIO is provided
+ then externally enable control will be considered.
+-maxim,dvs-gpio: GPIO which is connected to DVS pin of device.
+-maxim,dvs-default-state: Default state of GPIO during initialisation.
+ 1 for HIGH and 0 for LOW.
+-maxim,enable-remote-sense: boolean, enable reote sense.
+-maxim,enable-falling-slew-rate: boolean, enable falling slew rate.
+-maxim,enable-active-discharge: boolean: enable active discharge.
+-maxim,enable-frequency-shift: boolean, enable 9% frequency shift.
+-maxim,enable-bias-control: boolean, enable bias control. By enabling this
+ startup delay can be reduce to 20us from 220us.
+-maxim,enable-etr: boolean, enable Enhanced Transient Response.
+-maxim,enable-high-etr-sensitivity: boolean, Enhanced transient response
+ circuit is enabled and set for high sensitivity. If this
+ property is available then etr will be enable default.
+
+Enhanced transient response (ETR) will affect the configuration of CKADV.
+
+-junction-warn-millicelsius: u32, junction warning temperature threshold
+ in millicelsius. If die temperature crosses this level then
+ device generates the warning interrupts.
+
+Please note that thermal functionality is only supported on MAX77621. The
+supported threshold warning temperature for MAX77621 are 120 degC and 140 degC.
+
+Example:
+
+ max8973@1b {
+ compatible = "maxim,max8973";
+ reg = <0x1b>;
+
+ regulator-min-microvolt = <935000>;
+ regulator-max-microvolt = <1200000>;
+ regulator-boot-on;
+ regulator-always-on;
+ };
