235 PWM Spin-Up Cycle
238 A spin-up cycle occurs when a PWM output is commanded from 0% duty cycle to
239 some value > 0%. The LM93 supports a minimum duty cycle during spin-up. These
242 duration of the spin-up cycle is also configurable. These values are found in
244 the spin-up time in seconds. The available spin-up times are constrained by
248 Spin-up Durations:
264 Fan Boost
267 For each temperature channel, there is a boost temperature: if the channel
268 exceeds this limit, the LM93 will immediately drive both PWM outputs to 100%.
269 This limit is expressed in degrees C in the sysfs files temp<n>_auto_boost.
270 There is also a hysteresis temperature for this function: after the boost
271 limit is reached, the temperature channel must drop below this value before
272 the boost function is disabled. This temperature is also expressed in degrees
279 four tach input pins. GPIO0-GPIO3 correspond to (fan) tach 1-4, respectively.
