So far the driver reported the voltage on VAUX as "vout2". This was not entirely appropriate as it is not an output voltage, and complicates the code. Use the new virtual "VMON" register set and report the voltage as "vmon" instead. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Description
|
|
-----------
|
|
|
|
This driver supports hardware montoring for National Semiconductor LM25066,
|
|
LM5064, and LM5064 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.
