Thus the board dts files could add property for these nodes.

You should also add pmdomain driver.

I've encountered a similar issue before.
Finley told me to use the new PMIC, and that would solve the problem.
Maybe you're using the same old PMIC as I did :)

I don't know what does new PMIC mean? New RK806 driver or new RK806
hardware?

The problem is these power domains rely on voltage supply which could
be probed late after pmdomain driver, then the system enables the PD and
access the IP without PD actually enabled(even w/o voltage supply
enabled).
