platform/x86: mlx-platform: Fix item counter assignment for MSN2700/ComEx system

2020-12-08T10:14:49Z

platform/x86: mlx-platform: Remove PSU EEPROM from MSN274x platform configuration

2020-11-26T14:26:22Z

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.

platform/x86: mlx-platform: Add capability field to platform FAN description

2020-10-07T21:21:04Z

Set 'capability' field to FAN core platform data.. The content of 'capability' register allows to set the mapping between the drawers and tachometers. The motivation is to avoid adding a new code in the future in order to distinct between the systems types supporting a different kinds of the FAN drawers.
