Bindings for the Maxim MAX31760 Intelligent Fan Controller
|
|
==========================================================
|
|
|
|
The Maxim MAX31760 is a i2c device providing closed-loop, multi-channel fan
|
|
management with temperature. Various fan control features are provided,
|
|
including PWM frequency control, temperature hysteresis, dual tachometer
|
|
measurements, and fan health monitoring.
|
|
|
|
Required properties:
|
|
- compatible : should be "maxim,max31760".
|
|
- reg : I2C address, 0xa0.
|
|
|
|
Optional properties:
|
|
- maxim,vdd-supply : regulator supplying the vdd pin
|
|
- maxim,vdd-max-uv : regulator max voltage
|
|
- maxim,vdd-min-uv : regulator min voltage
|
|
- maxim,vdd-load-ua : regulator load current output
|
|
- maxim,vcca-supply : regulator supplying the vcca pin
|
|
- maxim,vcca-max-uv : regulator max voltage
|
|
- maxim,vcca-min-uv : regulator min voltage
|
|
- maxim,vcca-load-ua : regulator load current output
|
|
- maxim,pwr-en-gpio : fan enable gpio
|
|
|
|
Example:
|
|
max31760@50 {
|
|
compatible = "maxim,max31760";
|
|
reg = <0x50>;
|
|
maxim,vdd-supply = <&some_reg>;
|
|
regulator-names = "maxim,vdd";
|
|
maxim,vdd-max-uv = <3400000>;
|
|
maxim,vdd-min-uv = <3300000>;
|
|
maxim,vdd-load-ua = <300000>;
|
|
maxim,vcca-supply = <&some_reg>;
|
|
maxim,vcca-max-uv = <1800000>;
|
|
maxim,vcca-min-uv = <1800000>;
|
|
maxim,vcca-load-ua = <600000>;
|
|
maxim,pwr-en-gpio = <&some_gpio>;
|
|
};
