- 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.
