| |
| Description |
| ----------- |
| |
| This driver supports the MAX16601 VR13.HC Dual-Output Voltage Regulator |
| Chipset. |
| |
| 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. |
| |
| |
