1* Maxim MAX8973 Voltage Regulator
2
3Required 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
10Any standard regulator properties can be used to configure the single max8973
11DCDC.
12
13Optional 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
33Enhanced transient response (ETR) will affect the configuration of CKADV.

35Example:
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	};
