Subject: [PATCH v2 6/6] arm64: dts: uniphier: Stabilize Ethernet RGMII mode of PXs3 ref board
Date: Thu, 19 Mar 2020 16:50:52 +0900 [thread overview]
Message-ID: <1584604252-13172-7-git-send-email-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <1584604252-13172-1-git-send-email-hayashi.kunihiko@socionext.com>
The RGMII PHY needs to change drive-strength properties of the Ethernet
Tx pins to stabilize the PHY.
