Subject: [PATCH net-next v4 00/12] Add EMAC3 support for sa8540p-ride
Date: Tue, 11 Apr 2023 15:03:57 -0500	[thread overview]
Message-ID: <20230411200409.455355-1-ahalaney@redhat.com> (raw)

This is a forward port / upstream refactor of code delivered
downstream by Qualcomm over at [0] to enable the DWMAC5 based
implementation called EMAC3 on the sa8540p-ride dev board.

From what I can tell with the board schematic in hand,
as well as the code delivered, the main changes needed are:

    1. A new address space layout for dwmac5/EMAC3 MTL/DMA regs
    2. A new programming sequence required for the EMAC3 based platforms

This series makes the changes above as well as other housekeeping items
such as converting dt-bindings to yaml, etc.

As requested[1], it has been split up by compilation deps / maintainer tree.
I will post a link to the associated devicetree changes that together
with this series get the hardware functioning.

Patches 1-3 are clean ups of the currently supported dt-bindings and
IMO could be picked up as is independent of the rest of the series to
improve the current codebase. They've all been reviewed in prior
versions of the series.

Patches 5-7 are also clean ups of the driver and are worth picking up
independently as well. They don't all have explicit reviews but should
be good to go (trivial changes on non-reviewed bits).

The rest of the patches have new changes, lack review, or are specificly
being made to support the new hardware, so they should wait until the
series as a whole is deemed ready to go by the community.
