Subject: [PATCH v3 1/8] dt-bindings: net: meson-dwmac: Add the amlogic,rx-delay-ns property
Date: Tue, 12 May 2020 23:10:56 +0200 [thread overview]
Message-ID: <20200512211103.530674-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20200512211103.530674-1-martin.blumenstingl@googlemail.com>
The PRG_ETHERNET registers on Meson8b and newer SoCs can add an RX
delay. Add a property with the known supported values so it can be
configured according to the board layout.
