140 Temperatures are measured with 12-bit resolution and reported in millidegree
141 Celsius. The chip also features offsets for all 3 temperature inputs which -
142 when programmed - get added to the input readings. The chip does all the
144 need any user-space adjustments. The temperature inputs are mapped as follows
147 temp1: Remote diode 1 (3904 type) temperature -127C - +127C
148 temp2: DME1737 internal temperature -127C - +127C

160 Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
162 alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
164 generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
165 that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
166 attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
171 ------------------
173 This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
174 inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
175 1-3 can be configured to operate either in manual or automatic mode by setting
176 the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
177 in manual mode, their enable attributes are therefore read-only. When set to
178 manual mode, the fan speed is set by writing the duty-cycle value to the
180 current duty-cycle as set by the fan controller in the chip. All PWM outputs
183 In automatic mode, the chip supports the setting of the PWM ramp rate which
188 be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
190 pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
191 duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
192 and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
193 pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
194 programmed via zone[1-3]_auto_point[1-3]_temp and
195 zone[1-3]_auto_point1_temp_hyst:
198 pwm[1-3]_auto_point2_pwm full-speed duty-cycle (255, i.e., 100%)
199 pwm[1-3]_auto_point1_pwm low-speed duty-cycle
200 pwm[1-3]_auto_pwm_min min-speed duty-cycle
202 zone[1-3]_auto_point3_temp full-speed temp (all outputs)
203 zone[1-3]_auto_point2_temp full-speed temp
204 zone[1-3]_auto_point1_temp low-speed temp
205 zone[1-3]_auto_point1_temp_hyst min-speed temp
208 The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
211 auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
213 fan either turns completely off or keeps spinning with the low-speed
214 duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
215 all PWM outputs are set to 100% duty-cycle.
