Description
-----------
sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
temperature configuration points:
-* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
-* temp#_auto_temp_min - temperature over which fans start to spin.
-* temp#_auto_temp_max - temperature when fans spin at full speed.
-* temp#_auto_temp_crit - temperature when all fans will run full speed.
+* temp#_auto_temp_off
+ - temperature below which fans should be off or spinning very low.
+* temp#_auto_temp_min
+ - temperature over which fans start to spin.
+* temp#_auto_temp_max
+ - temperature when fans spin at full speed.
+* temp#_auto_temp_crit
+ - temperature when all fans will run full speed.
-* PWM Control
+PWM Control
+^^^^^^^^^^^
There are three PWM outputs. The LM85 datasheet suggests that the
pwm3 output control both fan3 and fan4. Each PWM can be individually
configured and assigned to a zone for its control value. Each PWM can be
configured individually according to the following options.
-* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
- temperature. (PWM value from 0 to 255)
+* pwm#_auto_pwm_min
+ - this specifies the PWM value for temp#_auto_temp_off
+ temperature. (PWM value from 0 to 255)
+
+* pwm#_auto_pwm_minctl
+ - this flags selects for temp#_auto_temp_off temperature
+ the behaviour of fans. Write 1 to let fans spinning at
+ pwm#_auto_pwm_min or write 0 to let them off.
-* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
- the behaviour of fans. Write 1 to let fans spinning at
- pwm#_auto_pwm_min or write 0 to let them off.
+.. note::
-NOTE: It has been reported that there is a bug in the LM85 that causes the flag
-to be associated with the zones not the PWMs. This contradicts all the
-published documentation. Setting pwm#_min_ctl in this case actually affects all
-PWMs controlled by zone '#'.

Configuration choices:
- Value Meaning
- ------ ------------------------------------------------
+========== =============================================
+Value Meaning
+========== =============================================
1 Controlled by Zone 1
2 Controlled by Zone 2
3 Controlled by Zone 3
0 PWM always 0% (off)
-1 PWM always 100% (full on)
-2 Manual control (write to 'pwm#' to set)
+========== =============================================
The National LM85's have two vendor specific configuration
features. Tach. mode and Spinup Control. For more details on these,
