Subject: arm64: dts: sprd: Add clock properties for serial devices
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=15d574fbd3f8ec7705896ed14b74eae482cadd4e;p=openwrt%2Fstaging%2Fblogic.git

arm64: dts: sprd: Add clock properties for serial devices

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.
