Description
|
|
-----------
|
|
|
|
This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
|
|
as well as the MAX16600, MAX16601, and MAX16602 VR13.HC Dual-Output
|
|
Voltage Regulator chipsets.
|
|
|
|
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.
|
|
|
|
|
|
Platform data support
|
|
---------------------
|
|
|
|
The driver supports standard PMBus driver platform data.
|
