+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)
