However if MMCX power domain is simply replaced to MXC one, it allows to turn titan_top_gdsc on successfully, even if MMCX is remained off according to /sys/kernel/debug/pm_genpd/pm_genpd_summary report. Note that at the moment qcom,sm8450-camcc.yaml gives a definite comment that the supply power domain should be MMCX, and it may be needed in some certain cases, but at the moment they are not unveiled on SM8550 platform.
