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
20 * "pwm" for PWM controller operating clock.
21 * "fan" for Fan controller operating clock.
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
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.
47 - cooling-levels: PWM duty cycle values in a range from 0 to 255
