It was described as a "ti,j721e-system-controller" but this is a J721S2 SoC with is not compatible with the system controller region found in J721e. No project consuming this DT has been found that makes use of the syscon compatible for this region, to prevent any from using this node like a generic syscon region in the future, make this a normal simple-bus as it should have been from the start.
