From c071afcea6ecf24a3c119f25ce9f71ffd55b5dc2 Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Wed, 23 Sep 2020 20:20:49 +0300 Subject: [PATCH] platform/x86: mlx-platform: Remove PSU EEPROM configuration 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.
