Then the rpmh driver can create the stats "device" at driver probe time, or just roll it into the same thing. It looks pretty weird to have a device in DT for this given that it's not really hardware, more like a place that the processor writes some stuff about what's going on in the SoC related to power management. > + # Example of rpm sleep stats > + - | > + rpm-sleep-stats@4690000 { > + compatible = "qcom,rpm-sleep-stats"; > + reg = <0 0x04690000 0 0x400>; > + }; > +...
