Description |
|
----------- |
|
|
|
This driver supports hardware monitoring for National Semiconductor / TI LM25056, |
|
LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring, |
|
Control, and Protection ICs. |
|
|
|
The driver is a client driver to the core PMBus driver. Please see |
|
Documentation/hwmon/pmbus.rst 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.rst for |
|
details. |
|
|
|
|
|
Platform data support |
|
--------------------- |
|
|
|
The driver supports standard PMBus driver platform data. |
|
|
|
|
|
