6Required properties:
7- compatible : One of "maxim,max6650" or "maxim,max6651"
8- reg        : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.

10Optional properties, default is to retain the chip's current setting:
11- maxim,fan-microvolt : The supply voltage of the fan, either 5000000 uV or
12			12000000 uV.
13- maxim,fan-prescale  : Pre-scaling value, as per datasheet [1]. Lower values
14			allow more fine-grained control of slower fans.
15			Valid: 1, 2, 4, 8, 16.
16- maxim,fan-target-rpm: Initial requested fan rotation speed. If specified, the
17			driver selects closed-loop mode and the requested speed.
18			This ensures the fan is already running before userspace
19			takes over.

21Example:
22	fan-max6650: max6650@1b {
23		reg = <0x1b>;
24		compatible = "maxim,max6650";
25		maxim,fan-microvolt = <12000000>;
26		maxim,fan-prescale = <4>;
27		maxim,fan-target-rpm = <1200>;
28	};
