117 Temperatures are measured with 12-bit resolution and reported in millidegree
118 Celsius. The chip also features offsets for all 3 temperature inputs which -
119 when programmed - get added to the input readings. The chip does all the
121 need any user-space adjustments. The temperature inputs are mapped as follows
124 temp1: Remote diode 1 (3904 type) temperature -127C - +127C
125 temp2: DME1737 internal temperature -127C - +127C
126 temp3: Remote diode 2 (3904 type) temperature -127C - +127C

137 Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
139 alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
141 generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
142 that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
143 attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
148 ------------------
150 This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
151 inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
152 1-3 can be configured to operate either in manual or automatic mode by setting
153 the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
154 in manual mode, their enable attributes are therefore read-only. When set to
155 manual mode, the fan speed is set by writing the duty-cycle value to the
157 current duty-cycle as set by the fan controller in the chip. All PWM outputs
165 be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
167 pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
168 duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
169 and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
170 pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
171 programmed via zone[1-3]_auto_point[1-3]_temp and
172 zone[1-3]_auto_point1_temp_hyst:
174 pwm[1-3]_auto_point2_pwm full-speed duty-cycle (255, i.e., 100%)
175 pwm[1-3]_auto_point1_pwm low-speed duty-cycle
176 pwm[1-3]_auto_pwm_min min-speed duty-cycle
178 zone[1-3]_auto_point3_temp full-speed temp (all outputs)
179 zone[1-3]_auto_point2_temp full-speed temp
180 zone[1-3]_auto_point1_temp low-speed temp
181 zone[1-3]_auto_point1_temp_hyst min-speed temp
183 The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
186 auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
188 fan either turns completely off or keeps spinning with the low-speed
189 duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
190 all PWM outputs are set to 100% duty-cycle.
