What: Legacy, non-standard chassis intrusion detection interface.
When: June 2011
Why: The adm9240, w83792d and w83793 hardware monitoring drivers have
legacy interfaces for chassis intrusion detection. A standard
interface has been added to each driver, so the legacy interface
can be removed.

This driver implements support for the hardware monitoring capabilities of the
SMSC DME1737 and Asus A8000 (which are the same), SMSC SCH5027, SCH311x,
and SCH5127 Super-I/O chips. These chips feature monitoring of 3 temp sensors
temp[1-3] (2 remote diodes and 1 internal), 7 voltages in[0-6] (6 external and
temp[1-3] (2 remote diodes and 1 internal), 8 voltages in[0-7] (7 external and
1 internal) and up to 6 fan speeds fan[1-6]. Additionally, the chips implement
up to 5 PWM outputs pwm[1-3,5-6] for controlling fan speeds both manually and
automatically.

Voltage pin mapping
-------------------
Here is a summary of the voltage pin mapping for the W83627THF. This
can be useful to convert data provided by board manufacturers into
working libsensors configuration statements.
W83627THF |
Pin | Name | Register | Sysfs attribute
-----------------------------------------------------
100 | CPUVCORE | 20h | in0
99 | VIN0 | 21h | in1
98 | VIN1 | 22h | in2
97 | VIN2 | 24h | in4
114 | AVCC | 23h | in3
61 | 5VSB | 50h (bank 5) | in7
74 | VBAT | 51h (bank 5) | in8
For other supported devices, you'll have to take the hard path and
look up the information in the datasheet yourself (and then add it
to this document please.)
