CONFIG_SENSORS_LM75: National Semiconductor LM75 and compatibles

General informations

The Linux kernel configuration item CONFIG_SENSORS_LM75 has multiple definitions:

National Semiconductor LM75 and compatibles found in drivers/hwmon/Kconfig

The configuration item CONFIG_SENSORS_LM75:

If you say yes here you get support for one common type of temperature sensor chip, with models including:

- Analog Devices ADT75 - Dallas Semiconductor DS75, DS1775 and DS7505 - Global Mixed-mode Technology (GMT) G751 - Maxim MAX6625 and MAX6626 - Microchip MCP980x - National Semiconductor LM75, LM75A - NXP's LM75A - ST Microelectronics STDS75 - ST Microelectronics STLM75 - TelCom (now Microchip) TCN75 - Texas Instruments TMP100, TMP101, TMP105, TMP112, TMP75, TMP175, TMP275

This driver supports driver model based binding through board specific I2C device tables.

It also supports the "legacy" style of driver binding. To use that with some chips which don't replicate LM75 quirks exactly, you may need the "force" module parameter.

This driver can also be built as a module. If so, the module will be called lm75.

If you say yes here you get support for National Semiconductor LM75 sensor chips and clones: Dallas Semiconductor DS75 and DS1775 (in 9-bit precision mode), and TelCom (now Microchip) TCN75.

The DS75 and DS1775 in 10- to 12-bit precision modes will require a force module parameter. The driver will not handle the extra precision anyhow.

This driver can also be built as a module. If so, the module will be called lm75.

If you say yes here you get support for National Semiconductor LM75 sensor chips and clones: Dallas Semi DS75 and DS1775, TelCon TCN75, and National Semi LM77. This can also be built as a module which can be inserted and removed while the kernel is running.

The module will be called lm75.

You will also need the latest user-space utilties: you can find them in the lm_sensors package, which you can download at http://www.lm-sensors.nu
