Please see 72Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 73 74 75Usage Notes 76----------- 77 78This driver does not auto-detect devices. You will have to instantiate the 79devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for 80details. 81 82 83Platform data support 84--------------------- 85 86The driver supports standard PMBus driver platform data. 87 88 89Sysfs entries 90------------- 91 92The following attributes are supported.
