-fan subnode format:
-===================
-Under fan subnode can be upto 8 child nodes, each child node representing a fan.
-Each fan subnode must have one PWM channel and at least one Fan tach channel.
-
-For PWM channel can be configured cooling-levels to create cooling device.
-Cooling device could be bound to a thermal zone for the thermal control.
-
-Required properties for each child node:
-- reg : specify the PWM output channel.
-	integer value in the range 0 through 7, that represent
-	the PWM channel number that used.
-
-- fan-tach-ch : specify the Fan tach input channel.
-		integer value in the range 0 through 15, that represent
-		the fan tach channel number that used.
-
-		At least one Fan tach input channel is required
-
-Optional property for each child node:
-- cooling-levels: PWM duty cycle values in a range from 0 to 255
-                  which correspond to thermal cooling states.
