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