*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

              configured to measure 5.0V power supply. Default is 3.3V.



Example:



lm87@2e {

	compatible = "ti,lm87";

	reg = <0x2e>;

	has-temp3;

	vcc-supply = <&reg_5v0>;

};
