If you say yes here you get support for National Semiconductor LM75
|
||||
sensor chips and clones: Dallas Semiconductor DS75 and DS1775 (in
|
||||
9-bit precision mode), and TelCom (now Microchip) TCN75.
|
||||
If you say yes here you get support for one common type of
|
||||
temperature sensor chip, with models including:
|
||||
|
||||
The DS75 and DS1775 in 10- to 12-bit precision modes will require
|
||||
a force module parameter. The driver will not handle the extra
|
||||
precision anyhow.

|

This driver supports driver model based binding through board
|
||||
specific I2C device tables.
|
||||
|
||||
It also supports the "legacy" style of driver binding. To use
|
||||
that with some chips which don't replicate LM75 quirks exactly,
|
||||
you may need the "force" module parameter.
|
||||
|
||||
This driver can also be built as a module. If so, the module
|
||||
will be called lm75.
