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?

It is new RK806 hardware. According to Finley, end users are currently using
this new type of PMIC.

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).

If I'm not mistaken, the new hardware will automatically powers up the supply
corresponding to VDEC/VNEC.

Thanks for the clarification on the hardware update.

I'm currently using the EVB board for SoC bring-up and post-silicon
validation, which I believe carries the old RK806 hardware. It's also
apparent that many developers (as opposed to end users) are still
relying on the old hardware in the field.

Generally speaking, upstream code has no way to distinguish between the old and new PMIC variants solely from the DTS, correct? Given this, I
think we should aim to keep both hardware versions workable in the
upstream code.

As far as I know, only early EVBs internal to Rockchip used them.
I think your approach also makes sense :)
