39 * init boolean
42     Use 'init=1' to have the driver do extra software initializations.
44     and depend on the BIOS to properly setup the chip. If you know you
45     have a w83791d and you're having problems, try init=1 before trying
46     reset=1.
48 * reset boolean
51     Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
52     behavior is no chip reset to preserve BIOS settings.
57     to force the subclients of chip 0x2f on bus 0 to i2c addresses

68 internal state that allows no clean access (Bank with ID register is not
70 parameter; this will put it into a more well-behaved state first.
78 on until the temperature falls below the Hysteresis value.
91 PWM 1-3 support Thermal Cruise mode, in which the PWMs are automatically
92 regulated to keep respectively temp 1-3 at a certain target temperature.

127 The sysfs-interface is documented in the 'sysfs-interface' file. Only
128 chip-specific options are documented here.

138 temp[1-3]_target	defines the target temperature for Thermal Cruise mode.
142 temp[1-3]_tolerance	temperature tolerance for Thermal Cruise mode.
