1 Kernel driver w83l786ng 2 ===================== 3 4 Supported chips: 5 * Winbond W83L786NG/W83L786NR 6 Prefix: 'w83l786ng' 7 Addresses scanned: I2C 0x2e - 0x2f 8 Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L786NRNG09.pdf 9 10 Author: Kevin Lo <kevlo@kevlo.org> 11 12 13 Module Parameters 14 ----------------- 15 16 * reset boolean 17 (default 0) 18 Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default 19 behavior is no chip reset to preserve BIOS settings 20 21 22 Description 23 ----------- 24 25 This driver implements support for Winbond W83L786NG/W83L786NR chips. 26 27 The driver implements two temperature sensors, two fan rotation speed 28 sensors, and three voltage sensors. 29 30 Temperatures are measured in degrees Celsius and measurement resolution is 1 31 degC for temp1 and temp2. 32 33 Fan rotation speeds are reported in RPM (rotations per minute). Fan readings 34 readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 35 or 128 for fan 1/2) to give the readings more range or accuracy. 36 37 Voltage sensors (also known as IN sensors) report their values in millivolts. 38 An alarm is triggered if the voltage has crossed a programmable minimum 39 or maximum limit. 40 41 /sys files 42 ---------- 43 44 pwm[1-2] - this file stores PWM duty cycle or DC value (fan speed) in range: 45 0 (stop) to 255 (full) 46 pwm[1-2]_enable - this file controls mode of fan/temperature control: 47 * 0 Manual Mode 48 * 1 Thermal Cruise 49 * 2 Smart Fan II 50 * 4 FAN_SET 51 pwm[1-2]_mode - Select PWM of DC mode 52 * 0 DC 53 * 1 PWM 54 tolerance[1-2] - Value in degrees of Celsius (degC) for +- T
