hwmon: New driver for the SMSC EMC6W201
This is a new driver for the SMSC EMC6W201 hardware monitoring device.
The device is functionally close to the EMC6D100 series, but is
register-incompatible.

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. | ||

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 | ||
