1 Kernel driver emc6w201 2 ====================== 3 4 Supported chips: 5 * SMSC EMC6W201 6 Prefix: 'emc6w201' 7 Addresses scanned: I2C 0x2c, 0x2d, 0x2e 8 Datasheet: Not public 9 10 Author: Jean Delvare <jdelvare@suse.de> 11 12 13 Description 14 ----------- 15 16 From the datasheet: 17 18 "The EMC6W201 is an environmental monitoring device with automatic fan 19 control capability and enhanced system acoustics for noise suppression. 20 This ACPI compliant device provides hardware monitoring for up to six 21 voltages (including its own VCC) and five external thermal sensors, 22 measures the speed of up to five fans, and controls the speed of 23 multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note 24 that it is possible to control more than three fans by connecting two 25 fans to one PWM output. The EMC6W201 will be available in a 36-pin 26 QFN package." 27 28 The device is functionally close to the EMC6D100 series, but is 29 register-incompatible. 30 31 The driver currently only supports the monitoring of the voltages, 32 temperatures and fan speeds. Limits can be changed. Alarms are not 33 supported, and neither is fan speed control. 34 35 36 Known Systems With EMC6W201 37 --------------------------- 38 39 The EMC6W201 is a rare device, only found on a few systems, made in 40 2005 and 2006. Known systems with this device: 41 * Dell Precision 670 workstation 42 * Gigabyte 2CEWH mainboard
