From mboxrd@z Thu Jan 1 00:00:00 1970 From: linus.walleij@linaro.org (Linus Walleij) Date: Thu, 8 Sep 2016 11:30:43 +0200 Subject: [PATCH 2/2] ARM: dts: add device tree for the RealView EB Rev D Message-ID: <1473327043-31903-1-git-send-email-linus.walleij@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The RealView EB revision D is a special case as it appears to be undocumented in ARM official documents, while the Linux kernel still contains special code for handling it. commit be4f3c8691492934c8ee03dbecb3a3a865ac6cd6 "Add RealView/EB support for the LAN9118 Ethernet chip" adds support for the SMSC LAN9118 chip used on the D revision, but no other traces of hardware deviations for this variant can be found. This created a separate top-level .dts file especially for this board version, so that it gets registered with the right type of ethernet controller.
