87 The chips implement 3 to 4 temperature sensors (9 for NCT6775F and NCT6776F),
90 and some automatic fan regulation strategies (plus manual fan control mode).
92 The temperature sensor sources on W82677HG-B, NCT6775F, and NCT6776F are
93 configurable. temp4 and higher attributes are only reported if its temperature
94 source differs from the temperature sources of the already reported temperature
95 sensors. The configured source for each of the temperature sensors is provided
100 resolution is 1 degC for W83667HG-B and 0.0 degC for NCT6775F and NCT6776F.
101 An alarm is triggered when the temperature gets higher than high limit;
102 it stays on until the temperature falls below the hysteresis value.
116 The driver supports automatic fan control mode known as Thermal Cruise.
117 In this mode, the chip attempts to keep the measured temperature in a
118 predefined temperature range. If the temperature goes out of range, fan
121 The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
124 temp1 -> pwm1
125 temp2 -> pwm2
126 temp3 -> pwm3 (not on 627UHG)
127 prog -> pwm4 (not on 667HG and 667HG-B; the programmable setting is not
