Ok. Let's try this:
pwm1 {0-255} Actual PWM/DAC value, single interface to
both registers.
pwm1_auto_pwm_min {0-255} Scaled to {0-15}, single interface to both
registers.
pwm1_enable {0-2} Fan control: off, manual, and automatic,
respectively
pwm1_mode {0-1} 0 (default) is PWM control of fans, 1 is DAC.
