3 The Nuvoton BMC NPCM7XX supports 8 Pulse-width modulation (PWM)
6 The Nuvoton BMC NPCM8XX supports 12 Pulse-width modulation (PWM)
9 Required properties for pwm-fan node
10 - #address-cells : should be 1.
11 - #size-cells	: should be 0.
12 - compatible	: "nuvoton,npcm750-pwm-fan" for Poleg NPCM7XX.
13 				: "nuvoton,npcm845-pwm-fan" for Arbel NPCM8XX.
14 - reg			: specifies physical base address and size of the registers.
15 - reg-names	: must contain:
18 - clocks		: phandle of reference clocks.
19 - clock-names	: must contain
22 - interrupts	: contain the Fan interrupts with flags for falling edge.
23 - pinctrl-names	: a pinctrl state named "default" must be defined.
24 - pinctrl-0	: phandle referencing pin configuration of the PWM and Fan
30 Each fan subnode must have one PWM channel and at least one Fan tach channel.
32 For PWM channel can be configured cooling-levels to create cooling device.
36 - reg : specify the PWM output channel.
40 - fan-tach-ch : specify the Fan tach input channel.
42 		the fan tach channel number that used.
44 		At least one Fan tach input channel is required
47 - cooling-levels: PWM duty cycle values in a range from 0 to 255
