    46 The PWM outputs are configurable but not via the driver. 
     46The PWM outputs are configurable via the driver. 
     47PWM values are from 0 to 255. The first value in the /proc entry is 
     48the pwm value; the second is the enable (0 or 1). 
     49 
     50The fan3 and pwm1 functions share a pin. 
     51If pwm1 is enabled than fan3 will read as 0.

    4753The Fan input types (2 wire or 3 wire) are configurable but

     526        pwm[1-4]: (not on w83781d) 
    527527          Controls the speed of the fans with PWM (Pulse Width Modulation) 
    528528          Valid values: 
    529529            0 - 255. 255 = max speed. 
    530  
    531         sensor[1-3]: (782d/783s only) 
     530        Second value is PWM enable 0/1. 
     531 
     532        sensor[1-3]: (not on w83781d) 
    532533          Controls the sensor type. To change to a different 
    533534          sensor type, for example, do 'echo 2 > sensor1'. 
     
    566567  782d and 783s pin is programmable for fan3 input or pwm2 output; 
    567568       defaults to fan3 input. 
    568        no control in driver so pwm2 doesn't work. 
     569       If pwm2 is enabled (with echo 255 1 > pwm2), then 
     570       fan3 will report 0.

    570572  782d has pwm1-2 for isa, pwm1-4 for i2c. (pwm3-4 share pins with
