    Subject[PATCH 5.4 186/408] platform/x86: mlx-platform: Remove PSU EEPROM configuration
    Date
    From: Vadim Pasternak <vadimp@nvidia.com>

    [ Upstream commit c071afcea6ecf24a3c119f25ce9f71ffd55b5dc2 ]

    Remove PSU EEPROM configuration for systems class equipped with
    Mellanox chip Spectrume-2. Till now all the systems from this class
    used few types of power units, all equipped with EEPROM device with
    address space two bytes. Thus, all these devices have been handled by
    EEPROM driver "24c32".
    There is a new requirement is to support power unit replacement by "off
    the shelf" device, matching electrical required parameters. Such device
    could be equipped with different EEPROM type, which could be one byte
    address space addressing or even could be not equipped with EEPROM.
    In such case "24c32" will not work.

    Fixes: 1bd42d94ccab ("platform/x86: mlx-platform: Add support for new 200G IB and Ethernet systems")
