1 Kernel driver max6639 2 ===================== 3 4 Supported chips: 5 * Maxim MAX6639 6 Prefix: 'max6639' 7 Addresses scanned: I2C 0x2c, 0x2e, 0x2f 8 Datasheet: http://pdfserv.maxim-ic.com/en/ds/MAX6639.pdf 9 10 Authors: 11 He Changqing <hechangqing@semptian.com> 12 Roland Stigge <stigge@antcom.de> 13 14 Description 15 ----------- 16 17 This driver implements support for the Maxim MAX6639. This chip is a 2-channel 18 temperature monitor with dual PWM fan speed controller. It can monitor its own 19 temperature and one external diode-connected transistor or two external 20 diode-connected transistors. 21 22 The following device attributes are implemented via sysfs: 23 24 Attribute R/W Contents 25 ---------------------------------------------------------------------------- 26 temp1_input R Temperature channel 1 input (0..150 C) 27 temp2_input R Temperature channel 2 input (0..150 C) 28 temp1_fault R Temperature channel 1 diode fault 29 temp2_fault R Temperature channel 2 diode fault 30 temp1_max RW Set THERM temperature for input 1 31 (in C, see datasheet) 32 temp2_max RW Set THERM temperature for input 2 33 temp1_crit RW Set ALERT temperature for input 1 34 temp2_crit RW Set ALERT temperature for input 2 35 temp1_emergency RW Set OT temperature for input 1 36 (in C, see datasheet) 37 temp2_emergency RW Set OT temperature for input 2 38 pwm1 RW Fan 1 target duty cycle (0..255) 39 pwm2 RW Fan 2 target duty cycle (0..255) 40 fan1_input R TACH1 fan tachometer input (in RPM) 41 fan2_input R TACH2 fan tachometer input (in RPM) 42 fan1_fault R Fan 1 fault 43 fan2_fault R Fan 2 fault 44 temp1_max_alarm R Alarm on THERM temperature on channel 1 45 temp2_max_alarm R Alarm on THERM temperature on channel 2 46 temp1_crit_alarm R Alarm on ALERT temperature on channel 1 47 temp2_crit_alarm R Alarm on ALERT temperature on channel 2 48 temp1_emergency_alarm R Alarm on OT temperature on channel 1 49 temp2_emergency_alarm R Alarm on OT temperature on channel 2
