NAME
 lmtemp — National Semiconductor LM75, LM77 and compatible hardware monitors
SYNOPSIS
 lmtemp0 at iic? addr 0x48 flags 0x0000
DESCRIPTION
 The 
lmtemp driver provides support for the National Semiconductor LM on iicbus series temperatures and register compatible chips to be used with the 
envsys(4) API. The 
lmtemp supports ranges of the temperature between +125 from -55.
Each device is specified by the value of the address and flags.
| Temperature | addr | flags | 
| LM75 | 0x48 - 0x4f | 0x0000 | 
| DS75 | 0x48 - 0x4f | 0x0001 | 
| LM77 | 0x48 - 0x4b | 0x0002 |
