-+About pwm[1-6]_enable
-+---------------------
-+0 - full-speed
-+    The chip doesn't have a specific way to set "full speed", so setting
-+    pwm[1-6]_enable to 0 is just "set PWM mode with 255 duty cycle".
-+1 - PWM mode
-+    Fan speed is controlled by writing a value to pwm[1-6].
-+2 - RPM mode
-+    Fan speed is controlled by writing a value to fan[1-6]_target.
-+
-+About fan[1-6]_fault
-+--------------------
-+In PWM (or full-speed) mode, if the input RPM goes below what is set
-+in fan[1-6]_target, fan[1-6]_fault gets set to 1. In other words,
-+fan[1-6]_target works as the minimum input RPM before a fan fault goes off.
-+
-+In RPM mode, fan fault is set when the fan spins "too slowly" (exact
-+conditions are in the datasheet). RPM mode depends on four variables:
-+    target_speed:        This is set by fan[1-6]_target.
-+    speed_range:         This is set automatically when setting target_speed
-+                         or manually by fan[1-12]_div.
-+    pwm_rate_of_change:  NOT set by the driver.
-+    fan_window:          NOT set by the driver.
-+
-+The last two values are not set by the driver, because there's no generic way to
-+compute them. You should set them manually through i2c (in the bootloader for
-+example). Check the datasheet for details.
-+
-+The fan fault value latches, to reset it, set a value to pwm[1-6]
-+or fan[1-6]_target.
-+
-+About fan[1-12]_div
-+-------------------
-+This value affects the measurable range of the chip. The driver sets this value
-+automatically in RPM based on fan[1-6]_target. In PWM mode, you should set this
-+value manually based on the details from the datasheet. Setting the speed range
-+is disabled while in RPM mode to prevent overwriting the automatically
-+calculated value.
