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. 34 35-junction-warn-millicelsius: u32, junction warning temperature threshold 36 in millicelsius. If die temperature crosses this level then 37 device generates the warning interrupts. 38 39Please note that thermal functionality is only supported on MAX77621. The 40supported threshold warning temperature for MAX77621 are 120 degC and 140 degC. 41 42Example: 43 44 max8973@1b { 45 compatible = "maxim,max8973"; 46 reg = <0x1b>; 47 48 regulator-min-microvolt = <935000>; 49 regulator-max-microvolt = <1200000>; 50 regulator-boot-on; 51 regulator-always-on; 52 }; 53
