25 | Description | |
26 | ----------- | |
27 | ||
28 | This driver supports hardware monitoring for below power supply devices | |
29 | which support PMBus Protocol: | |
30 | ||
31 | * BEL PFE1100 | |
32 | ||
33 | 1100 Watt AC to DC power-factor-corrected (PFC) power supply. | |
34 | PMBus Communication Manual is not publicly available. | |
35 | ||
36 | * BEL PFE3000 | |
37 | ||
38 | 3000 Watt AC/DC power-factor-corrected (PFC) and DC-DC power supply. | |
39 | PMBus Communication Manual is not publicly available. | |
40 | ||
41 | The driver is a client driver to the core PMBus driver. Please see | |
42 | Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
43 | ||
44 | ||
45 | Usage Notes | |
46 | ----------- | |
47 | ||
48 | This driver does not auto-detect devices. You will have to instantiate the | |
49 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
50 | details. | |
51 | ||
52 | Example: the following will load the driver for an PFE3000 at address 0x20 | |
53 | on I2C bus #1:: | |
54 | ||
55 | $ modprobe bel-pfe | |
56 | $ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | |
57 | ||
58 | ||
59 | Platform data support | |
60 | --------------------- | |
61 | ||
62 | The driver supports standard PMBus driver platform data. | |
