Some bootloadered disable unused power domains, so kernel code should
read the actual state from the hardware registers instead of assuming
that their initial state is 'on'.

As you said, if bootloader changed some hardware setting which is not
expected value in kernel, it should be notified to kernel. But for
pm_domaine->is_off, it should be via DT on EXYNOS now. As you know, the
functionality has been already implemented on dt.

Thanks.

Best regards,
Kgene.

I really doubt that we need such complex interface to pass the information 
which the driver can simply read from the register...
