Description
-----------

This driver implements support for several MAX6697 compatible temperature sensor
chips. The chips support one local temperature sensor plus four, six, or seven
remote temperature sensors. Remote temperature sensors are diode-connected
thermal transitors, except for MAX6698 which supports three diode-connected
thermal transistors plus three thermistors in addition to the local temperature
sensor.

The driver provides the following sysfs attributes. temp1 is the local (chip)
temperature, temp[2..n] are remote temperatures. The actually supported
per-channel attributes are chip type and channel dependent.

================ == ==========================================================
tempX_input      RO temperature
tempX_max        RW temperature maximum threshold
tempX_max_alarm  RO temperature maximum threshold alarm
tempX_crit       RW temperature critical threshold
tempX_crit_alarm RO temperature critical threshold alarm
tempX_fault      RO temperature diode fault (remote sensors only)
