- Kernel driver lm70
- ==================
- Supported chip:
- * National Semiconductor LM70
- Datasheet: http://www.national.com/pf/LM/LM70.html

- 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.

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