Kernel driver w83l786ng ======================= Supported chips: * Winbond W83L786NG/W83L786NR Prefix: 'w83l786ng' Addresses scanned: I2C 0x2e - 0x2f Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L786NRNG09.pdf Author: Kevin Lo Module Parameters ----------------- * reset boolean (default 0) Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default behavior is no chip reset to preserve BIOS settings Description ----------- This driver implements support for Winbond W83L786NG/W83L786NR chips. The driver implements two temperature sensors, two fan rotation speed sensors, and three voltage sensors. Temperatures are measured in degrees Celsius and measurement resolution is 1 degC for temp1 and temp2. Fan rotation speeds are reported in RPM (rotations per minute). Fan readings readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or 128 for fan 1/2) to give the readings more range or accuracy. Voltage sensors (also known as IN sensors) report their values in millivolts. An alarm is triggered if the voltage has crossed a programmable minimum or maximum limit. /sys files ---------- pwm[1-2] - this file stores PWM duty cycle or DC value (fan speed) in range: 0 (stop) to 255 (full) pwm[1-2]_enable - this file controls mode of fan/temperature control: * 0 Manual Mode * 1 Thermal Cruise * 2 Smart Fan II * 4 FAN_SET pwm[1-2]_mode - Select PWM of DC mode * 0 DC * 1 PWM tolerance[1-2] - Value in degrees of Celsius (degC) for +- T
