+
+ 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.
