73 The LM75 implements one temperature sensor. Limits can be set through the
74 Overtemperature Shutdown register and Hysteresis register. Each value can be
75 set and read to half-degree accuracy.
76 An alarm is issued (usually to a connected LM78) when the temperature
77 gets higher then the Overtemperature Shutdown value; it stays on until
78 the temperature falls below the Hysteresis value.
79 All temperatures are in degrees Celsius, and are guaranteed within a
80 range of -55 to +125 degrees.
82 The driver caches the values for a period varying between 1 second for the
83 slowest chips and 125 ms for the fastest chips; reading it more often
84 will do no harm, but will return 'old' values.
86 The original LM75 was typically used in combination with LM78-like chips
87 on PC motherboards, to measure the temperature of the processor(s). Clones
88 are now used in various embedded designs.
90 The LM75 is essentially an industry standard; there may be other
91 LM75 clones not listed here, with or without various enhancements,
92 that are supported. The clones are not detected by the driver, unless
93 they reproduce the exact register tricks of the original LM75, and must
94 therefore be instantiated explicitly. Higher resolution up to 16-bit
95 is supported by this driver, other specific enhancements are not.
97 The LM77 is not supported, contrary to what we pretended for a long time.
98 Both chips are simply not compatible, value encoding differs.
