1 Kernel driver menf21bmc_hwmon 2 ============================= 3 4 Supported chips: 5 6 * MEN 14F021P00 7 8 Prefix: 'menf21bmc_hwmon' 9 10 Addresses scanned: - 11 12 Author: Andreas Werner <andreas.werner@men.de> 13 14 Description 15 ----------- 16 17 The menf21bmc is a Board Management Controller (BMC) which provides an I2C 18 interface to the host to access the features implemented in the BMC. 19 20 This driver gives access to the voltage monitoring feature of the main 21 voltages of the board. 22 The voltage sensors are connected to the ADC inputs of the BMC which is 23 a PIC16F917 Mikrocontroller. 24 25 Usage Notes 26 ----------- 27 28 This driver is part of the MFD driver named "menf21bmc" and does 29 not auto-detect devices. 30 You will have to instantiate the MFD driver explicitly. 31 Please see Documentation/i2c/instantiating-devices.rst for 32 details. 33 34 Sysfs entries 35 ------------- 36 37 The following attributes are supported. All attributes are read only 38 The Limits are read once by the driver. 39 40 =============== ========================== 41 in0_input +3.3V input voltage 42 in1_input +5.0V input voltage 43 in2_input +12.0V input voltage 44 in3_input +5V Standby input voltage 45 in4_input VBAT (on board battery) 46 47 in[0-4]_min Minimum voltage limit 48 in[0-4]_max Maximum voltage limit 49 50 in0_label "MON_3_3V" 51 in1_label "MON_5V" 52 in2_label "MON_12V" 53 in3_label "5V_STANDBY" 54 in4_label "VBAT" 55 =============== ==========================
