+Bindings for MAX6651 and MAX6650 I2C fan controllers
+
+Reference:
+[1] https://datasheets.maximintegrated.com/en/ds/MAX6650-MAX6651.pdf
+
+Required properties:
+- compatible : One of "maxim,max6650" or "maxim,max6651"
+- reg : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.
+
+Optional properties, default is to retain the chip's current setting:
+- maxim,fan-microvolt : The supply voltage of the fan, sets the ADC range to
+ either 5V or 12V. Max value 13500000.
+- maxim,fan-prescale : Pre-scaling value, as per datasheet [1]. Lower values
+ allow more fine-grained control of slower fans.
+ Valid: 1, 2, 4, 8, 16.
+
+Example:
+ fan-max6650: max6650@1b {
+ reg = <0x1b>;
+ compatible = "maxim,max6650";
+ maxim,fan-microvolt = <12000000>;
+ maxim,fan-prescale = <4>;
+ };
