- 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.
