Suggest to use format: <vendor name>,<soc name>-<clk name>, look at the 
files under Documentation/devicetree/bindings/clock

For example:

starfive,jh7110-pll

For your case:

spacemit,k1-xxx

BTW, What's "CCU"?

Same as filename, compatible string should contain soc codename to 
differ from other soc of spacemit.
