The kernel shouldn't rely on U-Boot doing something to work, so please 
fix this with upstream Linux kernel.

Can you tell us what's the issue?

The issue with this patch here is that we probably would need **all** 
RK3588 boards to have the PMIC enabled, and all the appropriate 
regulators brought up before booting into the kernel. It'd be *much* 
better this is fixed in Linux (and depending on what we're talking 
about, it may need another fix in U-Boot so that whatever depends on the 
PM domain works as well).

Also, why the PMIC in SPL but not the regulators?

Cheers,
Quentin
