1Kernel driver lm70 2================== 3 4Supported chip: 5 * National Semiconductor LM70 6 Datasheet: http://www.national.com/pf/LM/LM70.html 7 8Author: 9 Kaiwan N Billimoria <kaiwan@designergraphix.com> 10 11Description 12----------- 13 14This driver implements support for the National Semiconductor LM70 15temperature sensor. 16 17The LM70 temperature sensor chip supports a single temperature sensor. 18It communicates with a host processor (or microcontroller) via an 19SPI/Microwire Bus interface. 20 21Communication with the LM70 is simple: when the temperature is to be sensed, 22the driver accesses the LM70 using SPI communication: 16 SCLK cycles 23comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's 24complement digital temperature (sent via the SIO line), is available in the 25driver for interpretation. This driver makes use of the kernel's in-core 26SPI support. 27 28Thanks to 29--------- 30Jean Delvare <khali@linux-fr.org> for mentoring the hwmon-side driver 31development. 32
