Kernel driver adp1050
=====================
Supported chips:
* Analog Devices ADP1050
Prefix: 'adp1050'
Addresses scanned: I2C 0x70 - 0x77
Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ADP1050.pdf
Authors:

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.
