| 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. |
