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