Please see24Documentation/hwmon/pmbus.rst for details on PMBus client drivers.25 26 27Usage Notes28-----------29 30This driver does not auto-detect devices. You will have to instantiate the31devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for32details.33 34 35Platform data support36---------------------37 38The driver supports standard PMBus driver platform data.39 40 41Sysfs entries42-------------43 44The following attributes are supported.
