Subject: [PATCH RFC 1/3] net: dt-bindings: add the amlogic,meson8b-dwmac binding
Date: Sat, 25 Jun 2016 18:50:11 +0200 [thread overview]
Message-ID: <20160625165013.15917-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20160625165013.15917-1-martin.blumenstingl@googlemail.com>
This patch adds the documentation for the DWMAC ethernet controller
found in Amlogic Meson 8b (S805) and GXBB (S905) SoCs.
Compared to the standard stmmac/dwmac configuration this requires some
some additional parameters for configuring the clock-generator
depending on the actual ethernet PHY on the board.
