Kernel driver bel-pfe ====================== Supported chips: * BEL PFE1100 Prefixes: 'pfe1100' Addresses scanned: - Datasheet: https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-pfe1100-12-054xa.pdf * BEL PFE3000 Prefixes: 'pfe3000' Addresses scanned: - Datasheet: https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-pfe3000-series.pdf Author: Tao Ren 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.
