20Description
21-----------
22
23This driver implements support for Intel Common Redundant Power supply with
24PMBus support.
25
26The driver is a client driver to the core PMBus driver.
27Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

30Usage Notes
31-----------
32
33This driver does not auto-detect devices. You will have to instantiate the
34devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
35details.
