25 | Description | |
26 | ----------- | |
27 | ||
28 | This driver supports hardware montoring for National Semiconductor LM25066, | |
29 | LM5064, and LM5064 Power Management, Monitoring, Control, and Protection ICs. | |
30 | ||
31 | The driver is a client driver to the core PMBus driver. Please see | |
32 | Documentation/hwmon/pmbus for details on PMBus client drivers. | |
33 | ||
34 | ||
35 | Usage Notes | |
36 | ----------- | |
37 | ||
38 | This driver does not auto-detect devices. You will have to instantiate the | |
39 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
40 | details. | |
41 | ||
42 | ||
43 | Platform data support | |
44 | --------------------- | |
45 | ||
46 | The driver supports standard PMBus driver platform data. | |
