51 -----------
52
53 This driver implements support for Texas Instr
54 TMP423, TMP441, and TMP442 temperature sensor
55 implement one local and up to one (TMP421, TMP
56 TMP442) or up to three (TMP423) remote sensors
57 in degrees Celsius. The chips are wired over I
58 over a temperature range of -40 to +125 degree
59 for both the local and remote channels is 0.06
60
61 The chips support only temperature measurement
62 the temperature values via the following sysfs
63
64 **temp[1-4]_input**
65
66 **temp[2-4]_fault**
67
68 Each sensor can be individually disabled via D
