Subject: [PATCH v2 3/4] arm64: dts: rockchip: Define drive-impedance-ohm for RK3399's emmc-phy.
Date:   Thu,  7 Mar 2019 09:41:55 +0100
Message-Id: <20190307084159.25236-3-christoph.muellner@theobroma-systems.com>
In-Reply-To: <20190307084159.25236-1-christoph.muellner@theobroma-systems.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A previous patch introduced the property 'drive-impedance-ohm'
for the RK3399's emmc phy node. This patch sets this value
explicitly to the default value of 50 Ohm.
