1	* Maxim MAX8973 Voltage Regulator
2	
3	Required properties:
4	
5	- compatible:	must be one of following:
6				"maxim,max8973"
7				"maxim,max77621".
8	- reg:		the i2c slave address of the regulator. It should be 0x1b.
9	
10	Any standard regulator properties can be used to configure the single max8973
11	DCDC.
12	
13	Optional properties:
14	
15	-maxim,externally-enable: boolean, externally control the regulator output
16			enable/disable.
17	-maxim,enable-gpio: GPIO for enable control. If the valid GPIO is provided
18			then externally enable control will be considered.
19	-maxim,dvs-gpio: GPIO which is connected to DVS pin of device.
20	-maxim,dvs-default-state: Default state of GPIO during initialisation.
21			1 for HIGH and 0 for LOW.
22	-maxim,enable-remote-sense: boolean, enable reote sense.
23	-maxim,enable-falling-slew-rate: boolean, enable falling slew rate.
24	-maxim,enable-active-discharge: boolean: enable active discharge.
25	-maxim,enable-frequency-shift: boolean, enable 9% frequency shift.
26	-maxim,enable-bias-control: boolean, enable bias control. By enabling this
27			startup delay can be reduce to 20us from 220us.
28	-maxim,enable-etr: boolean, enable Enhanced Transient Response.
29	-maxim,enable-high-etr-sensitivity: boolean, Enhanced transient response
30			circuit is enabled and set for high sensitivity. If this
31			property is available then etr will be enable default.
32	
33	Enhanced transient response (ETR) will affect the configuration of CKADV.
34	
35	Example:
36	
37		max8973@1b {
38			compatible = "maxim,max8973";
39			reg = <0x1b>;
40	
41			regulator-min-microvolt = <935000>;
42			regulator-max-microvolt = <1200000>;
43			regulator-boot-on;
44			regulator-always-on;
45		};
