*LM87 hwmon sensor.
Required properties:
- compatible: Should be
"ti,lm87"
- reg: I2C address
optional properties:
- has-temp3: This configures pins 18 and 19 to be used as a second
remote temperature sensing channel. By default the pins
are configured as voltage input pins in0 and in5.
- has-in6: When set, pin 5 is configured to be used as voltage input
in6. Otherwise the pin is set as FAN1 input.
- has-in7: When set, pin 6 is configured to be used as voltage input
in7. Otherwise the pin is set as FAN2 input.
- vcc-supply: a Phandle for the regulator supplying power, can be
cofigured to measure 5.0V power supply. Default is 3.3V.
Example:
lm87@2e {
compatible = "ti,lm87";
reg = <0x2e>;
has-temp3;
vcc-supply = <&reg_5v0>;
};
