I changed the CPU frequency by rewriting /boot/pine64/sun50i-a64-pine64-pinebook.dtb.
Create a dts file with the dtc command of the device-tree-compiler package.
I rewritten the dts file and created the dtb file with the dtc command.

It became dtb which does not boot with device-tree-compiler package of PINEBOOK (Ubuntu 16.04.2 LTS aarch64).
Creating dts/dtb using Debian sid amd64 's device-tree-compiler package worked fine.

Code:
pinebook$ cp /boot/pine64/sun50i-a64-pine64-pinebook.dtb sun50i-a64-pine64-pinebook.dtb.org

Code:
debian$ sudo apt install device-tree-compiler
debian$ dtc -I dtb sun50i-a64-pine64-pinebook.dtb.org -O dts -o sun50i-a64-pine64-pinebook.dts
debian$ vi sun50i-a64-pine64-pinebook.dts
debian$ dtc -I dtb sun50i-a64-pine64-pinebook.dtb.org -O dts | diff -u - ./sun50i-a64-pine64-pinebook.dts
