| This driver implements support for the National Semiconductor LM70 |
| 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 |
| Jean Delvare <khali@linux-fr.org> for mentoring the hwmon-side driver |
