| 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. | |
| Sysfs entries | |
