1 Kernel driver menf21bmc_hwmon 2 ============================= 3 4 Supported chips: 5 * MEN 14F021P00 6 Prefix: 'menf21bmc_hwmon' 7 Adresses scanned: - 8 9 Author: Andreas Werner <andreas.werner@men.de> 10 11 Description 12 ----------- 13 14 The menf21bmc is a Board Management Controller (BMC) which provides an I2C 15 interface to the host to access the features implemented in the BMC. 16 17 This driver gives access to the voltage monitoring feature of the main 18 voltages of the board. 19 The voltage sensors are connected to the ADC inputs of the BMC which is 20 a PIC16F917 Mikrocontroller. 21 22 Usage Notes 23 ----------- 24 25 This driver is part of the MFD driver named "menf21bmc" and does 26 not auto-detect devices. 27 You will have to instantiate the MFD driver explicitly. 28 Please see Documentation/i2c/instantiating-devices for 29 details. 30 31 Sysfs entries 32 ------------- 33 34 The following attributes are supported. All attributes are read only 35 The Limits are read once by the driver. 36 37 in0_input +3.3V input voltage 38 in1_input +5.0V input voltage 39 in2_input +12.0V input voltage 40 in3_input +5V Standby input voltage 41 in4_input VBAT (on board battery) 42 43 in[0-4]_min Minimum voltage limit 44 in[0-4]_max Maximum voltage limit 45 46 in0_label "MON_3_3V" 47 in1_label "MON_5V" 48 in2_label "MON_12V" 49 in3_label "5V_STANDBY" 50 in4_label "VBAT"
