    Subject[PATCH 5.10 212/717] platform/x86: mlx-platform: Remove PSU EEPROM from MSN274x platform configuration
    Date
    From: Vadim Pasternak <vadimp@nvidia.com>

    [ Upstream commit 912b341585e302ee44fc5a2733f7bcf505e2c86f ]

    Remove PSU EEPROM configuration for systems class equipped with
    Mellanox chip Spectrum and ATOM CPU - system types MSN274x. 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 "24c02".

    There is a new requirement is to support power unit replacement by "off
    the shelf" device, matching electrical required parameters. Such device
    can 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 "24c02" will not work.
