* hwmon: Add MCP3021 ADC driverXie Xiaobo2012-03-231-0/+1
| | | | | | | | | | | | | Add I2C driver for MCP3021 that is an ADC chip from Microchip. The MCP3021 is a successive approximation A/D converter (ADC) with 10-bit resolution. The driver export the value of Vin to sysfs, the voltage unit is mV. Through the sysfs interface, lm-sensors tool can also display Vin voltage.

In this release, the following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473, and NCP15WL333. This driver is based on the datasheet of MURATA. The driver in the patch does conversion from the raw ADC value (either voltage or resistence) to temperature. In order to use voltage values as input, the circuit schematics should be provided with the platform data. A compensation table for each type of thermistor is provided for the conversion.

* | hwmon: New driver sch5636Hans de Goede2011-07-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new driver for SMSC SCH5636 Super I/O chips. The chips include an embedded microcontroller for hardware monitoring solutions, allowing motherboard manufacturers to create their own custom hwmon solution based upon the SCH5636. Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based hwmon solution. The sch5636 driver runs a sanity check on loading to ensure it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based hwmon solution.

The driver dumps package level thermal information through sysfs interface so that upper level application (e.g. lm_sensor) can retrive the information. Instead of having the package level hwmon code in coretemp, I write a seperate driver pkgtemp because: First, package level thermal sensors include not only sensors for each core, but also sensors for uncore, memory controller or other components in the package. Logically it will be clear to have a seperate hwmon driver for package level hwmon to monitor wider range of sensors in a package. Merging package thermal driver into core thermal driver doesn't make sense and may mislead. Secondly, merging the two drivers together may cause coding mess. It's easier to include various package level sensors info if more sensor information is implemented. Coretemp code needs to consider a lot of legacy machine cases. Pkgtemp code only considers platform starting from Sandy Bridge. On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp: pkgtemp-isa-0000 Adapter: ISA adapter physical id 0: +33.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0002 Adapter: ISA adapter Core 2: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0003 Adapter: ISA adapter Core 3: +32.0°C (high = +79.0°C, crit = +99.0°C) [ hpa: folded v3 patch removing improper global variable "SHOW" ] Signed-off-by: Fenghua Yu <fenghua.yu@intel.com> LKML-Reference: <1280448826-12004-3-git-send-email-fenghua.yu@intel.com> Reviewed-by: Len Brown <len.brown@intel.com> Signed-off-by: H.

* hwmon: Driver for TI TMP102 temperature sensorSteven King2010-05-271-0/+1
| | | | | | | | | | | | | | | Driver for the TI TMP102. The TI TMP102 is similar to the LM75. It differs from the LM75 by having a 16-bit conf register and the temp registers have a minimum resolution of 12 bits; the extended conf register can select 13-bit resolution (which this driver does) and also change the update rate (which this driver currently doesn't use).
