+Kernel driver menf21bmc_hwmon
+Supported chips:
+ * MEN 14F021P00
+ Prefix: 'menf21bmc_hwmon'
+ Adresses scanned: -
+Author: Andreas Werner <>
+The menf21bmc is a Board Management Controller (BMC) which provides an I2C
+interface to the host to access the features implemented in the BMC.
+This driver gives access to the voltage monitoring feature of the main
+voltages of the board.
+The voltage sensors are connected to the ADC inputs of the BMC which is
+a PIC16F917 Mikrocontroller.
+Usage Notes
+This driver is part of the MFD driver named "menf21bmc" and does
+not auto-detect devices.
+You will have to instantiate the MFD driver explicitly.
+Please see Documentation/i2c/instantiating-devices for
+Sysfs entries
+The following attributes are supported. All attributes are read only
+The Limits are read once by the driver.
