* Provide a detect function if and only if a chip can be detected reliably.
* Only the following I2C addresses shall be probed: 0x18-0x1f, 0x28-0x2f,
0x48-0x4f, 0x58, 0x5c, 0x73 and 0x77. Probing other addresses is strongly
discouraged as it is known to cause trouble with other (non-hwmon) I2C
chips. If your chip lives at an address which can't be probed then the
device will have to be instantiated explicitly (which is always better
anyway.)
* Avoid writing to chip registers in the detect function. If you have to write,
only do it after you have already gathered enough data to be certain that the
detection is going to be successful.

The driver implements three temperature sensors, seven fan rotation speed
sensors, nine voltage sensors, and two automatic fan regulation
strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
synchronized with selected fan (fan1-fan3). This functionality and manual PWM
control for fan4-fan7 is not yet implemented.
The driver also implements up to seven fan control outputs: pwm1-7. Pwm1-7
can be configured to PWM output or Analogue DC output via their associated
pwmX_mode. Outputs pwm4 through pwm7 may or may not be present depending on
how the W83792AD/D was configured by the BIOS.
Automatic fan control mode is possible only for fan1-fan3.
For all pwmX outputs, a value of 0 means minimum fan speed and a value of
255 means maximum fan speed.
Temperatures are measured in degrees Celsius and measurement resolution is 1
degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
