-*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>;
-};
