Subject: [PATCH v2 0/8] Add support for ICSSG-based Ethernet on SR1.0 devices
Date: Wed, 17 Jan 2024 16:14:54 +0000	[thread overview]
Message-ID: <20240117161602.153233-1-diogo.ivo@siemens.com> (raw)

Hello,

This series extends the current ICSSG-based Ethernet driver to support
Silicon Revision 1.0 devices.

Notable differences between the Silicon Revisions are that there is
no TX core in SR1.0 with this being handled by the firmware, requiring
extra DMA channels to communicate commands to the firmware (with the
firmware being different as well) and in the packet classifier.

The motivation behind it is that a significant number of Siemens
devices containing SR1.0 silicon have been deployed in the field
and need to be supported and updated to newer kernel versions
without losing functionality.

This series is based on TI's 5.10 SDK [1].

The first version of this patch series can be found in [2].

Changes in v2:
 - Addressed Krzysztof's comments on the dt-binding
 - Removed explicit references to SR2.0
 - Added static keyword as indicated by the kernel test robot
