Thanks your notice. Unfortunately, we still have no chance let patch
with these two clock merged. The last version is [1]. This clock patch
will block cpufreq dts [2] and dynamic power dts [3]. Clock maintainer
is working on new architecture [4], hopefully we can send new clock
patch soon. After that, we will send new cpufreq and dynamic power dts.
So please ignore [2] [3] at this moment.
