Description |
|
----------- |
|
|
|
This driver supports hardware monitoring for below power supply devices |
|
which support PMBus Protocol: |
|
|
|
* BEL PFE1100 |
|
|
|
1100 Watt AC to DC power-factor-corrected (PFC) power supply. |
|
PMBus Communication Manual is not publicly available. |
|
|
|
* BEL PFE3000 |
|
|
|
3000 Watt AC/DC power-factor-corrected (PFC) and DC-DC power supply. |
|
PMBus Communication Manual is not publicly available. |
|
|
|
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. |
|
|
|
Example: the following will load the driver for an PFE3000 at address 0x20 |
|
on I2C bus #1:: |
|
|
|
$ modprobe bel-pfe |
|
$ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device |
|
|
|
|
|
Platform data support |
|
--------------------- |
|
|
|
The driver supports standard PMBus driver platform data. |
