-Description
------------
-
-This driver implements support for the National Semiconductor LM70
-temperature sensor.
-
-The LM70 temperature sensor chip supports a single temperature sensor.
-It communicates with a host processor (or microcontroller) via an
-SPI/Microwire Bus interface.
-
-Communication with the LM70 is simple: when the temperature is to be sensed,
-the driver accesses the LM70 using SPI communication: 16 SCLK cycles
-comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
-complement digital temperature (sent via the SIO line), is available in the
-driver for interpretation. This driver makes use of the kernel's in-core
-SPI support.
-
-As a real (in-tree) example of this "SPI protocol driver" interfacing
-with a "SPI master controller driver", see drivers/spi/spi_lm70llp.c
-and its associated documentation.
-
-The TMP121/TMP123 are very similar; main differences are 4 wire SPI inter-
-face (read only) and 13-bit temperature data (0.0625 degrees celsius reso-
-lution).

-Thanks to
----------
-Jean Delvare <khali@linux-fr.org> for mentoring the hwmon-side driver
-development.
