Bindings for a fan connected to the PWM lines

Required properties:
- compatible : "pwm-fan"
- pwms : the PWM that is used to control the PWM fan
- cooling-levels : PWM duty cycle values in a range from 0 to 255
which correspond to thermal cooling states

Optional properties:
- fan-supply : phandle to the regulator that provides power to the fan
- interrupts : This contains an interrupt specifier for each fan
tachometer output connected to an interrupt source.
The output signal must generate a defined number of
interrupts per fan revolution, which require that
it must be self resetting edge interrupts. See
interrupt-controller/interrupts.txt for the format.
- pulses-per-revolution : define the number of pulses per fan revolution for
each tachometer input as an integer (default is 2
interrupts per revolution). The value must be
greater than zero.

Example:
fan0: pwm-fan {
compatible = "pwm-fan";
#cooling-cells = <2>;
pwms = <&pwm 0 10000 0>;
cooling-levels = <0 102 170 230>;
};

thermal-zones {
cpu_thermal: cpu-thermal {
thermal-sensors = <&tmu 0>;
polling-delay-passive = <0>;
polling-delay = <0>;
trips {
cpu_alert1: cpu-alert1 {
temperature = <100000>; /* millicelsius */
hysteresis = <2000>; /* millicelsius */
type = "passive";
};
};
cooling-maps {
map0 {
trip = <&cpu_alert1>;
cooling-device = <&fan0 0 1>;
};
};
};

Example 2:
fan0: pwm-fan {
compatible = "pwm-fan";
pwms = <&pwm 0 40000 0>;
fan-supply = <&reg_fan>;
interrupt-parent = <&gpio5>;
interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
pulses-per-revolution = <2>;
};

Example 3:
fan0: pwm-fan {
compatible = "pwm-fan";
pwms = <&pwm1 0 25000 0>;
interrupts-extended = <&gpio1 1 IRQ_TYPE_EDGE_FALLING>,
<&gpio2 5 IRQ_TYPE_EDGE_FALLING>;
pulses-per-revolution = <2>, <1>;
};
