43 | Description | |
44 | ----------- | |
45 | ||
5c9353f5 | 46 | This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743 |
cce20958 GR |
47 | Integrated, Step-Down Switching Regulators with PMBus support. |
48 | ||
49 | The driver is a client driver to the core PMBus driver. | |
50 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
51 | ||
52 | ||
53 | Usage Notes | |
54 | ----------- | |
55 | ||
56 | This driver does not auto-detect devices. You will have to instantiate the | |
57 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
58 | details. | |
