Description
|
|
-----------
|
|
|
|
This driver supports hardware montoring for National Semiconductor / TI LM25056,
|
|
LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
|
|
Protection ICs.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus 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 for
|
|
details.
|
|
|
|
|
|
Platform data support
|
|
---------------------
|
|
|
|
The driver supports standard PMBus driver platform data.
|
|
|
|
|
|
