31 | Description | |
32 | ----------- | |
33 | ||
58615a94 GR |
34 | This driver supports hardware montoring for National Semiconductor / TI LM25056, |
35 | LM25066, LM5064, and LM5064 Power Management, Monitoring, Control, and | |
36 | Protection ICs. | |
03e9bd8d GR |
37 | |
38 | The driver is a client driver to the core PMBus driver. Please see | |
39 | Documentation/hwmon/pmbus for details on PMBus client drivers. | |
40 | ||
41 | ||
42 | Usage Notes | |
43 | ----------- | |
44 | ||
45 | This driver does not auto-detect devices. You will have to instantiate the | |
46 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
47 | details. | |
48 | ||
49 | ||
50 | Platform data support | |
51 | --------------------- | |
52 | ||
53 | The driver supports standard PMBus driver platform data. | |
