I guess it is enabled by > the bootloader so we can't change it in runtime? > The reason for voting for the "proxy" resources is such that if apss power collapses we might cut the power before the firmware has had a chance to tell the RPMh to keep the power on. So, there is a chance that an unfortunately timed power collapse might cause the modem to loose power, but given that I can't poke mss.lvl I would expect that this is handled in some other way - if necessary... > > Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> > > Given that adsp remoteproc works without configuring mss power domain, > > Reviewed-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> > Thank you!
