- Kernel driver emc6w201
- ======================
- Supported chips:
- * SMSC EMC6W201
- Prefix: 'emc6w201'
- Addresses scanned: I2C 0x2c, 0x2d, 0x2e
- Datasheet: Not public
- Author: Jean Delvare <jdelvare@suse.de>
- Description
- -----------
- From the datasheet:
- "The EMC6W201 is an environmental monitoring device with automatic fan
- control capability and enhanced system acoustics for noise suppression.
- This ACPI compliant device provides hardware monitoring for up to six
- voltages (including its own VCC) and five external thermal sensors,
- measures the speed of up to five fans, and controls the speed of
- multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note
- that it is possible to control more than three fans by connecting two
- fans to one PWM output. The EMC6W201 will be available in a 36-pin
- QFN package."
- The device is functionally close to the EMC6D100 series, but is
- register-incompatible.
- The driver currently only supports the monitoring of the voltages,
- temperatures and fan speeds. Limits can be changed. Alarms are not
- supported, and neither is fan speed control.
- Known Systems With EMC6W201
- ---------------------------
- The EMC6W201 is a rare device, only found on a few systems, made in
- 2005 and 2006. Known systems with this device:
- * Dell Precision 670 workstation
- * Gigabyte 2CEWH mainboard
