Subject: [PATCH] arm64: dts: sprd: Add clock properties for serial devices
Date:   Wed, 10 Apr 2019 15:22:50 +0800
Message-Id: <1246f7a9ce912458ea3b889b0c0e392897a664c8.1554879978.git.baolin.wang@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We've introduced power management logics for the Spreadtrum serial
controller by commit 062ec2774c8a ("serial: sprd: Add power management
for the Spreadtrum serial controller"), thus add related clock properties
to support this feature.
