The MAX34451 supports monitoring voltage or current of 12 channels -based on GIN pins. The MAX34460 supports 12 voltage channels, and the MAX34461 -supports 16 voltage channels. - -The driver is a client driver to the core PMBus driver. Please see -Documentation/hwmon/pmbus for details on PMBus client drivers. - - -Usage Notes ------------ - -This driver does not auto-detect devices. You will have to instantiate the -devices explicitly. Please see Documentation/i2c/instantiating-devices for -details. - -For MAX34446, the value of the currX_crit attribute determines if current or -voltage measurement is enabled for a given channel. Voltage measurement is -enabled if currX_crit is set to 0; current measurement is enabled if the -attribute is set to a positive value. Power measurement is only enabled if -channel 1 (3) is configured for voltage measurement, and channel 2 (4) is -configured for current measurement. - - -Platform data support ---------------------- - -The driver supports standard PMBus driver platform data. - - -Sysfs entries -------------- - -The following attributes are supported.
