13 | Description | ||
14 | ----------- | ||
15 | |||
16 | This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply | ||
17 | Controller with Active-Voltage Output Control and PMBus Interface. | ||
18 | |||
19 | The driver is a client driver to the core PMBus driver. | ||
20 | Please see Documentation/hwmon/pmbus for details on PMBus client drivers. | ||
21 | |||
22 | |||
23 | Usage Notes | ||
24 | ----------- | ||
25 | |||
26 | This driver does not auto-detect devices. You will have to instantiate the | ||
27 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | ||
28 | details. | ||
29 | |||
30 | |||
31 | Platform data support | ||
32 | --------------------- | ||
33 | |||
34 | The driver supports standard PMBus driver platform data. | ||
