Some dts properties are missing in Linux dts. E.g:
- The clock dts information is not upstreamed in Linux yet.
- CCU node is not in Linux dts (Linux doesn't need to initialize CCU)
- Compatible string for rstmgr is different in Linux and Uboot.

So, there are some differences in Linux vs Uboot dts/dtsi.
I can remove Linux commit ID in commit message if it is confusing.
