I think they might take the power sequence into account when they were
introducing the devices, vdda-phy(~0.9v) first and vdda-pll(1.2v)

the downstream. BTW, the DSDT is unreliable. On my platform, it
describes that several components are consuming several LDOs, but
these components work well with these LDOs manually disabled via rpmh.

Hmm looks like schematics would trump these speculations. Maybe wait until this can be confirmed.
