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.
