Kernel driver lm95234=====================Supported chips: * National Semiconductor / Texas Instruments LM95234 Addresses scanned: I2C 0x18, 0x4d, 0x4e Datasheet: Publicly available at the Texas Instruments website http://www.ti.com/product/lm95234Author: Guenter Roeck <linux@roeck-us.net>Description-----------LM95234 is an 11-bit digital temperature sensor with a 2-wire System ManagementBus (SMBus) interface and TrueTherm technology that can very accurately monitorthe temperature of four remote diodes as well as its own temperature.The four remote diodes can be external devices such as microprocessors,graphics processors or diode-connected 2N3904s. The LM95234's TruThermbeta compensation technology allows sensing of 90 nm or 65 nm processthermal diodes accurately.All temperature values are given in millidegrees Celsius. Temperatureis provided within a range of -127 to +255 degrees (+127.875 degrees forthe internal sensor). Resolution depends on temperature input and range.Each sensor has its own maximum limit, but the hysteresis is common to allchannels. The hysteresis is configurable with the tem1_max_hyst attribute andaffects the hysteresis on all channels. The first two external sensors alsohave a critical limit.The lm95234 driver can change its update interval to a fixed set of values.It will round up to the next selectable interval. See the datasheet for exactvalues. Reading sensor values more often will do no harm, but will return'old' values.
