This driver implements support for Texas Instruments TMP401, TMP411,

TMP431, and TMP432 chips. These chips implement one or two remote and

one local temperature sensors. Temperature is measured in degrees

and one local temperature sensors. Temperature is measured in degrees

Celsius. Resolution of the remote sensor is 0.0625 degree. Local

sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not

supported by the driver so far, so using the default resolution of 0.5

	  If you say yes here you get support for Texas Instruments TMP401,

	  TMP411, TMP431, and TMP432 temperature sensor chips.

	  TMP411, TMP431, TMP432 and TMP435 temperature sensor chips.



	  This driver can also be built as a module.  If so, the module

	  will be called tmp401.
