| Description |
| ----------- |
| |
| This driver supprts hardware monitoring for Analog Devices ADP1050 Digital |
| Controller for Isolated Power Supply with PMBus interface. |
| |
| The ADP1050 is an advanced digital controller with a PMBus™ |
| interface targeting high density, high efficiency dc-to-dc power |
| conversion used to monitor system temperatures, voltages and currents. |
| Through the PMBus interface, the device can monitor input/output voltages, |
| input current and temperature. |
| |
| 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. |
