SPDX-License-Identifier: GPL-2.0 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: - Radu Sabau 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.
