Notes:
Changes since v1:
As suggested include all the changes are moved in
to the same patch and the all the optional properties
are now defined instead of using a single variable to
indicate those properties.
Changes since v2:
Changed has-vcc-5v to use regulator binding and fixed
a minor copy paste mistake.
Changes since v3:
Update the vcc-supply description.

+*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 = <®_5v0>;
+};
