+Optional properties:
10
+- fan-supply		: phandle to the regulator that provides power to the fan
11
+- interrupts		: This contains a single interrupt specifier which
12
+			  describes the tachometer output of the fan as an
13
+			  interrupt source. The output signal must generate a
14
+			  defined number of interrupts per fan revolution, which
15
+			  require that it must be self resetting edge interrupts.
16
+			  See interrupt-controller/interrupts.txt for the format.
17
+- pulses-per-revolution : define the tachometer pulses per fan revolution as
18
+			  an integer (default is 2 interrupts per revolution).
19
+			  The value must be greater than zero.
20
+- rockchip,temp-trips	: The property is an array of 2-tuples items, and
21
+			  each item consists of temperature in millicelsius and
22
+			  pwm cooling state. This depends on CONFIG_ROCKCHIP_SYSTEM_MONITOR.
23
+			  If add the property the fan cooling state will be changed
24
+			  by system monitor. Otherwise, use the default thermal governor.
