70Description
71-----------
72
73This driver implements support for several MAX6697 compatible temperature sensor
74chips. The chips support one local temperature sensor plus four, six, or seven
75remote temperature sensors. Remote temperature sensors are diode-connected
76thermal transistors, except for MAX6698 which supports three diode-connected
77thermal transistors plus three thermistors in addition to the local temperature
78sensor.
79
80The driver provides the following sysfs attributes. temp1 is the local (chip)
81temperature, temp[2..n] are remote temperatures. The actually supported
82per-channel attributes are chip type and channel dependent.

84================ == ==========================================================
85tempX_input      RO temperature
86tempX_max        RW temperature maximum threshold
87tempX_max_alarm  RO temperature maximum threshold alarm
88tempX_crit       RW temperature critical threshold
89tempX_crit_alarm RO temperature critical threshold alarm
90tempX_fault      RO temperature diode fault (remote sensors only)
