This is truly required for msm8996 SoCs? The code I'm looking at doesn't try to get these power domains for 8996 so presumably you're breaking backward compatibility with old device tree files by making this required now. I don't personally know how widespread msm8996 usage is w/ upstream, so I'd let Bjorn comment on whether he thinks this is OK. As with the other patches in this series, I personally prefer less prose and more lists / tables of exactly what is required for which compatible string. > + reference to the list of 4 power-domains for the modem > + sub-system on SDM845 SoCs > + > +- power-domain-names: > + Usage: required > + Value type: <stringlist> > + Definition: must be "cx", "mx" for the modem sub-system on MSM8996 > + SoCs > + must be "cx", "mx", "mss", "load_state" for the modem > + sub-system on SDM845 SoCs I haven't see a patch for using "load_state". Can you point at it? I guess this was "aop" in your last version? -Doug
