49 The LM93 hardware monitor has a two wire digital interface compatible with
50 SMBus 2.0. Using an 8-bit ADC, the LM93 measures the temperature of two remote
52 voltages. To set fan speed, the LM93 has two PWM outputs that are each
68 --------------
72 The LM93 can monitor two #PROCHOT signals. The results are found in the
78 exponential moving average (but not quite - check the datasheet). Note
80 from 0-255 where 0 indicates no throttling, and 255 indicates > 99.6%.
82 The monitoring intervals for the two #PROCHOT signals is also configurable.
91 It is possible to configure the LM93 to logically short the two #PROCHOT
93 assert #P2_PROCHOT, and vice-versa. This mode is enabled by writing a
94 non-zero integer to the sysfs file prochot_short.
110 The LM93 can monitor two #VRD_HOT signals. The results are found in the
113 files are read-only.
119 If a fan is driven using a low-side drive PWM, the tachometer
132 The LM93 has a fixed or override mode for the two PWM outputs (although, there
133 are still some conditions that will override even this mode - see section
137 and pwm2 are used to set the manual duty cycle; each is an integer (0-255)

200 There is an independent base temperature for each temperature channel. Note,
201 however, there are only two tables of offsets: one each for temp[12] and
206 oscillation between two steps in the offsets table. These values are found in

216 PWM Spin-Up Cycle:
218 A spin-up cycle occurs when a PWM output is commanded from 0% duty cycle to
219 some value > 0%. The LM93 supports a minimum duty cycle during spin-up. These
222 duration of the spin-up cycle is also configurable. These values are found in
224 the spin-up time in seconds. The available spin-up times are constrained by
228 Spin-up Durations: 0 (disabled, h/w default), 0.1, 0.25, 0.4, 0.7, 1.0,
234 channel, the LM93 will ramp the PWM output up to 100% duty cycle in discrete
235 steps. The duration of each step is configurable. There are two files, with
244 For each temperature channel, there is a boost temperature: if the channel
248 limit is reached, the temperature channel must drop below this value before
