- Description
- -----------
- This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
- as well as the MAX16601 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
