Subject: [PATCH v2 3/3] sh_eth: add R8A77980 support
Date: Fri, 18 May 2018 21:32:46 +0300 [thread overview]
Message-ID: <a0dec765-3196-c09d-b41c-c1eb3025a8ad@cogentembedded.com> (raw)
In-Reply-To: <f30c98ff-f6da-9e7f-c637-49076a428885@cogentembedded.com>
Finally, add support for the DT probing of the R-Car V3H (AKA R8A77980) --
it's the only R-Car gen3 SoC having the GEther controller -- others have
only EtherAVB...
Based on the original (and large) patch by Vladimir Barinov.
