Probe for DPU silently fails, with CONFIG_DEBUG_DRIVER=3Dy we get this: msm-mdss ae00000.mdss: __genpd_dev_pm_attach() failed to find PM domain: -2 While I'm not familiar with the specifics of fw_devlink, the dtsi has power-domains =3D <&dispcc MDSS_GDSC> for this node but it doesn't pick that up for some reason. We can also see that a bit later dispcc finally probes. Regards Luca > Regards, > > Tony
