I'll send a new patch with changing binding document.

What does the meaning of existing bindings are used anywhere? Do you
mean this binding is used by other SoCs ?

Currently scpsys driver can't be shared between different Mediatek SoCs
because the power domains are different from each other. So I think it
should no need to maintain backward compatibility on scpsys's binding.

OK.
