The RK3399 SoC needs to know the voltage value provided by some regulators, which is done by setting relevant register bits. Configure these the way other RK3399 boards do, but with the same values as are set in the equivalent code in coreboot.

There is a driver for this on Rockchip's repo, I managed to forward-port it and get it working. If that's more desirable than doing it per-board like this I can send that upstream (but I'd prefer to do it after this).

This looks like a board hack code for me, which is difficult to maintain in the long run. Better go with UCLASS_POWER_DOMAIN, I believe it would be a straightforward implementation.
Yeah, it's a board hack that several other boards also do. I've got a driver working for this as mentioned above, but that adds a new UCLASS_IO_DOMAIN instead of using UCLASS_POWER_DOMAIN like you suggest.
I had been tired of carrying these patches, so wanted to get any working version merged before attempting to upstream the driver and remove the hacky parts from all boards at once. I'm not sure how long would that take, and I didn't want this to be blocked by that.
I've got to work on binman things for a while, so I might not be able to get to that and your other suggestions soon enough.
